Stefan&#x27;s Bitcoin 1x1

2Mon

@Ash since the account @boz seems to be gone (or he blocked me) and with him the comments and I don't know if you got my answer, here is my answer about the node:

I recently upgraded my node
given my node an upgrade :)
If you like, I'll find you the products
that I ordered. My old Raspi 4 was constantly overheating and the hard disk was almost full...
Then I swapped it for a Raspi 5.
I would actually recommend building it yourself, otherwise it will be very expensive. A finished node costs around 400-500€... There were always some in the FulmoShop and on Nerdminer.de I think there is also a ready-made one. Basically, you only need a small Raspberry Pi (4 or 5), an SSD hard disk (at least 1TB, better 2), a 32GB SD card and a cable to connect the hard disk to the Raspi:)

Nothing can really happen. You then download the Raspiblitz or Umbrel software and load it onto the SD card. Then insert the SD card into the Rasperry Pi and switch it on.

That's it

@stefan_21 Now that's what I call a service post! 🥰
So you're not just playing with my feelings after all 😉
A finished node wouldn't be worth €400-500 to me either. Just think how much $BTC I could buy for that. 😅
How expensive is it to buy the individual components?
I've become a bitcoin cheapskate and ask myself before every purchase: Do I really need this? And: How many sats would I get for it? 🤣

•

2Mon

@Ash I can understand that, it's the same for me😂
I have the Raspi 5 with 8GB RAM. But 4GB would theoretically be enough. I ordered all the components individually. But I just saw that there's also a bundle:
https://www.amazon.de/Raspberry-Starter-Kit-Netzteil-Geh%C3%A4use-L%C3%BCfter/dp/B0CRPF47RG/

You would then only need an SSD, for example
https://www.amazon.de/SanDisk-schnelleres-Herunterfahren-Lesegeschwindigkeit-Schreibgeschwindigkeit/dp/B07YFFJK2Q/

And then you would need a cable to connect the SSD to the Raspi, something like that:
https://www.amazon.de/Retoo-Adapter-Konverter-Externer-Festplatte/dp/B0CL6KSYLL/ref=sr_1_7?

If I've calculated correctly, that would be around €260 in total. You might be able to find a cheaper SSD and the 4GB Raspi would also be enough for the pure node. However, I also wanted to run a mining pool for my small Bitaxe and possibly set up a Lightning Node again. That's why I preferred the larger version :)

•

2Mon

@stefan_21 All right, I'll have a look at everything next week and then certainly come back with a few more questions. ❤️

•

2Mon

@Testo-Investor about the Node - see my chat with @Ash from a few days ago :)

•

2Mon

@stefan_21 then the fun costs around 500€ correct? I'll have a look at everything at my leisure. Sounds mega exciting in any case! Have you calculated how high the electricity costs are per day?

•

2Mon

@Testo-Investor Exactly, the Node around 260€ and the Bitaxe 189€ with the code WASBITCOINBRINGT (is from the podcast of the same name by Niko Jilch)
The current from the Raspi is around 3-5 watts and the Bitaxe now runs relatively constantly at 20-21 watts. If we roughly calculate with 25 watts, you get 18 cents per day at 30ct per KWh. That's just under €5 per month

•

2Mon

@stefan_21 I'll just come along to your node :-)

2Mon

@Testo-Investor shouldn't be a problem in theory either😂 You should also be able to open the mining pool externally. But I'll have to see how that works first

Thanks, cool idea with the post!

I have one question right away:
You explained the time bug in the Bitcoin Fun Facts - couldn't you just leave it out, since we have our own "time" in the network with the block height? And that is information from outside and is therefore subject to the oracle problem anyway, right?

•

9Mon

@vise72 On the one hand, you're absolutely right, but no, you couldn't leave it out :D
This time is needed for the Difficulty Adjustment, which looks at whether the last 2016 blocks were found faster or slower than an average of 10 minutes :)

•

V7Hodl@V7Hodl

9Mon

@stefan_21 Right, thanks for the explanation - but how is it ensured that the miners don't enter a completely wrong time and thus manipulate the Difficulty Adjustment?

••

9Mon

@vise72 There are two factors that play a role here. Firstly, the miner cannot set the timestamp arbitrarily in the past because the nodes only accept blocks where the timestamp is greater than the median timestamp of the last 11 blocks. Furthermore, the timestamp may not extend more than 2 hours into the future relative to the time of the nodes.

So let's assume it is 13:00 for me according to my node and a miner finds a block with the timestamp 15:01 - then my node would reject this block :)

Many thanks for your valuable contributions @stefan_21! I have now also found my way to Strike.me. Thanks for that too!
Perhaps you can answer a question that I have not yet been able to solve.
With the hourly savings plan, Bitcoin is always bought at the same price - "not at the actual price". How does this price come about? Thank you and LG

•

8Mon

@Aggregation Hi :) I almost missed your comment😅
It can't actually be that the price at which you buy Bitcoin with the hourly savings plan is the same every time - is that still the case?
I had the hourly savings plan running for a while and the market price was simply taken every hour as normal (minus the fees in the first week)

•

Aggregation@Aggregation

8Mon

@stefan_21 Basically, it is not always the same, but as an example, today it has 6x at exactly 84,745.76€, 3x 84,033.61 and the other transactions distributed over 2 other prices such as 83,333.33€
That's what I meant by always at the same price. The question I have now is, where do these prices come from and shouldn't he actually buy at the actual price at that time. Thanks for your feedback. 🙏

@Aggregation I just clicked through the old transactions of the hourly savings plan and I had a different price every time. So that's quite strange and I didn't have that.
What you could do, of course, would be to ask customer service. I've had two questions so far and received a competent answer within a few hours :)

Greetings Stefan, I registered with Strike via your ref link. Your contributions are really first class, please continue!

I have one question for you: From the point of view of a convinced Bitcoin maximalist (I assume ;) ) what do you think of $XMR and the $KAS hyped on getquin ?

I only own $BTC myself, but the thought of exchanging my fiat for one of these coins is growing day by day. By the way, I think absolutely nothing of shipcoins like $ETH, $SOL, $XRP and so on.

•

6Mon

@gqx Hi :)
First of all, thank you very much for the praise and for using my ref link!

I see XMR as fundamentally positive in terms of privacy - but it won't work. XMR will never become money or will only ever be used in the darknet corner. Monero has already been taken down on many exchanges and is no longer tradable.
The path of a non-state asset only works in one direction. First, something has to be accepted by the masses as a store of value, then at some point it will be used more and more as a means of transaction because people want it. And finally, if it is used as a means of transaction to a sufficient extent, it becomes a unit of account and thus money.
With Monero, it already fails at point 1, the widely accepted store of value...

The Kaspa people claim that they have solved the blockchain trilemma. Unfortunately, they have again only sacrificed decentralization for scalability. According to the Kaspa Wiki, you need at least 1 TB of storage and 32 GB of RAM to operate a Kaspa node - and the trend is rising sharply. So hardly anyone will be able to afford to simply run their own node at home - and to keep it constantly supplied with new hardware. This is why Kaspa has so few nodes and why the network will become increasingly centralized. Bitcoin has a block size limit for precisely this reason and scales in a second layer :)
In addition, Kaspa also runs on Proof of Work - which is basically positive, but POW is a "winner takes it all" algo, which is why Kaspa will not be able to exist alongside Bitcoin in the long term.

Roughly speaking, these are the reasons why I think these projects will fail in the long term. But that doesn't mean that there isn't still price potential. I mean, look how all those stupid memecoins are going through the roof😂

If you want to speculate, feel free to put a small amount into altcoins - I don't see anything wrong with that. It's just important to have a healthy skepticism and not to "fall in love" with these projects. In the long term, these projects will all go to zero compared to Bitcoin - but in the short term, these altcoins can outperform Bitcoin from time to time due to their low market capitalization.

•

gqx@gqx

6Mon

@stefan_21 Thanks for the detailed answer! I've already donated a couple of beers to you via Strike (€4.20) ;)

Well, then I have some closure: at $XMR I already knew that the money would be shifted directly back into $BTC, as it is limited to this darknet space. I don't see any growth potential for a "trade" there either. The adaptation rate is far too low precisely because of the high entry hurdles and will remain low.

Now to Kaspa: During my research on the $MARA share, I learned that they have also started mining other POW coins such as $KAS in addition to $BTC. This surprised me a little and I dived straight into the Kaspa bubble. However, this one doesn't really give any counter-arguments against the project either, which is why I turned to a non-hyperbullish source (you). Your points seem conclusive to me!

You also dismissed the idea of other POW coins replacing our good old $BTC in your answer. Would you like to explain to me in more detail how POW is a "winner takes it all" algo? Sure, $BTC has the first-mover advantage, but I would also like to be prepared with an argument when the next highly praised "POW-based Bitcoin killer" appears on the market.

•

@gqx it was you :D thank you! I'll drink the next beer to you🫶
You'll get a reply from me later regarding the POW issue and Kaspa - if I forget, please just tag me again😅 Just a bit stressed at work today due to a system changeover

•

6Mon

@gqx So now I'll give it a try :)

First of all: As you know, PoW networks are based on computing power, which secures them. Miners who invest their resources act economically rational. They use their hash power where the highest security, the greatest long-term benefit and the best profit are given - and that is the case with Bitcoin, by far the most established and secure network with the largest user base. Miners would not risk retooling their investments in specialized, expensive hardware for a network that has yet to prove itself.

It is not the case that Mara and Co. can simply "switch" their computing power to another network. ASIC computers that are optimized for Bitcoin can only do one thing: hash SHA-256 - and extremely efficiently at that.

Kaspa is - as far as I know - based on a completely different mining algorithm that is optimized for GPUs in particular. This would force miners to completely abandon their existing investments and purchase new hardware. This would not only be mega costly, but also risky because a small network like Kaspa is much more vulnerable to attacks.

And this is where the real "Winner Takes It All" phenomenon of PoW networks comes into play: The network effects ensure that the more participants a large network has, the more attractive it becomes. More miners and users mean greater security and more trust, which in turn attracts more participants. It's a self-reinforcing cycle :)

At the same time, as already mentioned, the economic incentive plays a role, as miners invest enormous sums in specialized hardware and only use it where it is worthwhile in the long term. A network with a low hashrate, as is the case with new PoW projects, not only offers less security, but is also less profitable with an uncertain future - and therefore unattractive for miners.

In addition, network security is closely linked to the growth of a coin. Smaller networks are much more susceptible to attacks, such as 51% attacks. This creates further uncertainty.

This dynamic means that computing power and user activity are almost inevitably concentrated on the most profitable and secure network. PoW coins with a significantly lower hashrate have little chance of overtaking Bitcoin in the long term - either they will be displaced or they will centralize because only a few large miners will be able to secure the network. (Incidentally, this was also one of the reasons why ETH switched to Proof of Stake).

That's why I see PoW as a "winner takes it all" mechanism (it would probably be more accurate to say "winner takes most", as there are a few small POW coins that have been around for a while but don't play a role compared to the Bitcoin hashrate) and Bitcoin has an unassailable lead thanks to its network effects and ecosystem. A new PoW "Bitcoin killer" would find it extremely difficult to seriously jeopardize this dominance.
And extremely difficult is still an understatement😅

@stefan_21 That really opened my eyes! At first I thought that you could mine a coin at will and "switch" easily, but I didn't realize that it would involve so much cost and effort.

@stefan_21 What do you think of the following strategy, which I come across more and more often when I deal with the $BTC cycles?

-> At the end of a Bitcoin bull run, sell BTC and shift into established stablecoins to secure the value. During the bear market, you could use the stablecoins for lending, staking or yield farming to generate passive income. As soon as BTC has fallen sharply again, you could buy it back cheaply and profit from the next bull run.

Do you see any major risks or opportunities for optimization? Or do you perhaps do the same yourself?

Greetings and a kiss
Ash

@Ash As far as I know, the swap in stablecoins is not a tax-relevant transaction only in Austria. In Germany, it counts as a sale and the one-year speculation period starts all over again when you buy again.
So I don't really see the advantage of switching to stablecoins, as you are exposed to additional risks :)

It's better to hold them in euros and earn some interest😅 at least you have the deposit protection that applies. If the stablecoin implodes, you're out of luck.

The other problem, of course, is that nobody knows how long the bull market will last. And also whether the cycles of Bitcoin and the 70-80% setbacks will continue.
Timing this is incredibly difficult.

Personally, I just set myself targets where I sell a few percent. For example, you could sell 10% at 150k, 10% at 175k, 10% at 200k and hold the rest. Then you would have made a profit and still have at least 70% of your holdings at the end.
You could then use the fiat money to buy back at a lower price in a potential bear market.
If the bear market started before 150k and we needed 4 years until the next ATH, you would have to live with it and sit it out.

I always make an Excel list with my holdings and potential price targets. And then I enter something like in my example above and see what comes out. Then I see that I would have x€ and xBTC at a top of e.g. 160k and can then consider whether I could live with that.
And in this way you can think through the possible scenarios and find a strategy for yourself that you can live with considering all the possibilities :)

I hope that was reasonably clear - if not, please just ask again. That was typed very quickly - I'm just on my way to the shops😂

@stefan_21 Hello, my dear! I haven't read anything from you in the main feed for a while and just hope you're doing well. 😊

I'm currently looking into buying a Steelwallet and am completely overwhelmed by the sheer variety on offer - not to mention the price differences.

During my research, I came across this site, among others,

https://jlopp.github.io/metal-bitcoin-storage-reviews/

but the large selection doesn't really make it any easier. Do you have a Steelwallet, and if so, which one can you recommend?

I would also be happy to pass the question on to @Alpalaka and @DonkeyInvestor

I look forward to your feedback and hope you have a great Sunday!

•

@Ash Greetings! That's sweet of you - thank you, I'm fine - I hope you are too? :)
I'm going through a bit of a rough patch at the moment because of an illness in the family. But luckily we're quite confident now.
And if everything goes smoothly, my girlfriend and I will be going on vacation on Wednesday😊 So there is a chance of improvement :)
That's why I'll be relatively inactive here over the next few days.

Regarding the steel wallet, I have the Seedor. It came with a hammer and matching letters to punch in. It was super easy, but a bit noisy. I felt a bit sorry for my neighbors😂
So I could recommend it - unfortunately I can't say anything about the others because I haven't tried them myself :)

@Ash I have/had this one: https://shop.bitbox.swiss/de/products/steelwallet-13/
I'm happy with the plate, although the punch didn't always punch properly. But if you have an extra five minutes, that shouldn't be a problem

I've now made another one myself as I have access to steel + laser. But it's more of a gimmick

•

@stefan_21 Oh dear, I hope your family member is not seriously ill and that he/she gets back on his/her feet quickly! I can empathize, I have written on several occasions that someone in my family is also seriously ill. I'm keeping my fingers crossed for you and your family that the person will get better soon. 🍀

I had already looked at the Seedor. But holy moly, what a price they're charging! I'd rather buy Bitcoin from them. 😅

@Alpalaka has also shared his (cheaper) Steelwallet, and I'll see which of the two I might end up with.

In any case, I wish you and your better half a wonderful and relaxing vacation and hope you can recharge your batteries. 🔌⚡️

Best wishes Ash

It's me again about the ledger:

I wanted to get the Ledger Nano X (149.00€) and I still have a few questions...

- what do you think of the product?

- Is it easy to set up?

- Am I doing the right thing by transferring my btc's to the ledger, so that they disappear from my Strike app and are only on the ledger?

- Can I still see them in getquin in my portfolio overview?

Thank you and best regards!

•

3Mon

@MedusaFi Hi :)
If you don't have a Ledger yet, I would honestly advise against it. Ledger has already abused the trust of customers so often in the past that I, for example, no longer buy a Ledger.
You can also read the article here: https://getqu.in/2wY3eP/

The Nano X is certainly a good device. However, as I said, I am bothered by the manufacturer, the fact that it is not completely open source and the recover function, which stores your private key and therefore access to your Bitcoin in the cloud (how stupid). You can deactivate this function, but I find it hard that Ledger has programmed this in and sells it as an advantage.

I would rather recommend the BitBox02 or a Trezor :) Both are easy to use open source devices. If you want it to be cheaper, I could also recommend the Jade from Blockstream.

Exactly, if you send the Bitcoin from Strike to your wallet, they will no longer be displayed on Strike. Strike then no longer has access to your Bitcoin, but you do with the help of your own wallet.
Nothing should change in GetQuin during the transfer. You will probably have added the purchases manually, right? :)

@stefan_21 Thank you very much! I'll have a look at the BitBox02 :)
Yes, purchases were added manually.

•

@MedusaFi right, with the Mac but schon🤷‍♂️ BitBox is working on it - Apple is still a little reluctant. They don't release the USB-C port for external devices...
I have an Android smartphone, but I hardly ever use the BitBox with my smartphone. I always use the PC for that. But I also work on the PC, so it's running virtually all day anyway😅
You only need the wallet anyway to generate a new receiving address or to send something :)

•

@stefan_21 it's me again..😂now i also have the bitbox02, i am very satisfied. i still have a few questions:

- is it normal that the transaction on the bitbox app takes so long?
- do i have to leave the bitbox plugged in while a transaction is running?
- the important thing is the SD card, isn't it? then keep it safe, nobody else can access it with the BitBox alone, can they?

thanks and lg!!! :)

••

3Mon

@MedusaFi Hi :)
- It depends on what you mean by long and from where you made the transaction. Basically, it always works like this: The sender creates the transaction, sets the transaction fees that he is willing to pay, signs the transaction with his private key and then sends the transaction. The transaction then ends up in the mempool, where all unconfirmed or not yet executed transactions are collected. The miners take transactions from this pool (always the ones with the highest fees, as these go into their pockets) and use them to create a block. If they find a valid block, they can add it to the blockchain -> and only then is the transaction confirmed and only then do you have the Bitcoin on the Bitbox02. But it would be exactly the same with any other wallet :)

- No, you don't have to leave it plugged in. You can always receive transactions. It all runs on the blockchain on tens of thousands of computers worldwide. You can always receive and if you want to send, you can always do that, but you have to sign the transaction with your wallet beforehand so that the Bitcoin network recognizes it as valid.

- Correct, unless someone guesses your wallet pin in the 10 attempts you have. Then you would have access to the wallet even without an SD card. However, after 10 incorrect password entries, the content is deleted and can only be restored using the SD card or the 24 words.
Please write down your 24 words on paper and keep the note safe. Don't break the SD card - or the note. Keeping both in separate places is the best option. Later you could also stamp the words onto metal - this would also make them waterproof and fireproof. But this is only worthwhile for larger amounts.

I hope I was able to help you :)

No, you plug in the Bitaxe, then you connect to its WLAN and then you are automatically directed to the setup page. There you have to connect it to your home wifi, enter the pool and your user.
You have to enter the user in the format [Bitcoin address].
So bc12345678910.Testo for example :D
Then you join the mining pool under the name Testo and if you find a block it will be paid out to your BTC address.

@Testo-Investor but the bitaxe is running and shows that it is connected?
If so, you would have to look on your router to see which IP address the bitaxe is connected to.

@stefan_21 First of all, thank you for your great contributions on the subject of Bitcoin. I hadn't dealt with bitcoins intensively in the past, as it seemed too complex to me at first glance and I had mentally saved crypto in general as not serious/useful for a rather conservative investor like me.

After reading your Bitcoin series for beginners and following up on other of your posts, the second point in particular (seriousness) has largely been resolved in my mind - at least in relation to Bitcoin and not other cryptocurrencies.

The assessment of the complexity has remained the same, but I now have at least a basic understanding and would like to add bitcoins to my portfolio.

I had planned to proceed as follows:
- Savings plan of XX € per week
- Entry via 2-3 tranches in the mid four-digit range
- Purchase a hardware wallet for the initial tranches and for the automatic transfer of my Satoshis accumulated via the savings plan once they reach a certain cumulative value

Since I want to invest exclusively in Bitcoins in the crypto sector, I would also prefer providers who only trade Bitcoins.

I would choose 21bitcoin as my provider, as they have relatively low fees and also support a savings plan and the planned transfer to the hardware wallet. I also find the German-language support and Raiffeisenbank Bayern Mitte to be positive. With regard to Strike, I have read negative things in some forum posts regarding legitimization/proof of origin, otherwise I would have chosen Strike due to the attractive savings plan conditions.

With regard to the hardware wallet, I actually wanted to purchase the Bitbox02 in the Bitcoin-only edition directly from the manufacturer, although the Bitbox02 Nova can now also be pre-ordered, which would also be compatible with my iPhone, so I would prefer this. I will only use my iPhone and PC. You don't have an opinion on the Bitbox02 Nova yet, do you?

Security is important to me, but in my opinion, a hardware wallet with a separate companion app should be sufficient for the size of my planned investment. I would refrain from multisig / passphrase / punched seed phrase for the time being due to my still rather moderate investment volume. From what size would you consider this to be a mandatory additional security measure? I had roughly considered >0.25 bitcoins or when I reach a relevant asset share.

Do I need to pay attention to anything else before I start or have I misunderstood something from your point of view? I would appreciate a brief answer. Thanks again for introducing me to this topic!

•

@DanDoDan Hi :)
There's not much I can say for now, except that I think it's great how well you've dealt with the topic. In principle, you have a clear plan, both in terms of buying in tranches and via a savings plan, and in terms of custody. That's exactly how it should be! :)

As you say, 21Bitcoin is a great provider. The support is top, the fees are completely fine, the payout to your own wallet is very cheap and you can have the Bitcoin automatically paid out to your wallet from x amount. I always do this from around 2-3 million sats. In my opinion, these are suitable UTXO amounts for the future.

I now use the savings plan with Strike and - as things stand - I can't report anything negative about it. I haven't had to deal with certificates of origin or anything like that so far. But I only use my weekly savings plan there. I haven't made any major one-off purchases yet :)

Regarding hardware wallets:
You're definitely not going wrong with BitBox. If you have an iPhone, I would also go for the Nova. I don't have any practical experience with the Nova yet, but I know that the Nova is basically the same as the BitBox02. Only the IOS connection has been solved and the Nova has a better display and a newer, better secure chip. And I have only had positive experiences with the BitBox02.

Basically, the hardware wallet is enough for now. The only thing you could consider for the start would be to use a passphrase. Simply an additional password that you keep separate from the seed phrase or even just memorize.
The point is that if, for example, a burglar finds your seed phrase, they still won't be able to access your BTC holdings because they don't have the passphrase.
So this is not absolutely necessary, but it increases security even further by simple means :)

However, it is of course important that the more complex you make it - i.e. passphrase, multisig etc., the more likely you are to lose access to your Bitcoin. So you have to weigh things up a bit.

It is important for you to gain experience at the beginning. You can also start very simply with the hardware wallet and then at some point create a second wallet on your BitBox using a passphrase. Then you can make a transaction from one wallet to the other and vice versa. In my experience, this always helps a lot to get a feel for the device and how to use it.

It's also important that you don't just rely on the BitBox's SD card, but also write down the 24 words on paper and keep them safe. Not that the SD card will no longer be readable in 10 years and your BitBox will suddenly give up the ghost :D
And I also have a note about 21Bitcoin: it is not yet possible to send Bitcoin from your own hardware wallet to 21Bitcoin in order to sell it.
Although the feature has been announced and is planned (and will come as part of a successful MiCa license), it is not yet available. So if you want to sell Bitcoin on your hardware wallet, you will have to switch to another provider in the meantime.

Have fun and good luck! And if you have any other questions, please feel free to ask :)

@stefan_21 Many thanks for the quick reply. I'll think about the passphrase again, the cost/benefit ratio sounds good and sensible. The BitBox has been ordered and the account at 21bitcoin has been created. Thanks for pointing out that it is not yet possible to sell the coins on the hardware wallet via 21bitcoin. Even though I see bitcoins more as a long-term component of assets and less as trade goods, I would be interested to know how long you think it will take 21bitcoin to introduce this feature? The only thing I'm still unsure about is whether I should already buy 1-2 tranches in the next few days/weeks, even though the bitbox won't be delivered until the end of August.

@DanDoDan This is planned by 21Bitcoin and should actually be implemented within the next 2-3 months (i.e. by April) as of January. The background is probably that they need the MiCa license for this.
Now it's already July and the function still doesn't exist... I don't think it will take too much longer, but unfortunately I don't know any more details :)

You'll have to decide whether you want to wait to buy or go ahead with the first installments. I think the risk of 21Bitcoin being hacked and all Bitcoin being stolen by the end of August is very low - but not 0 :D
With the 4-5 weeks bridging time, I honestly wouldn't worry about it.

Watch to the end. 😎
