Mega contribution. Thanks for your assessment of the topic. I've only ever had the hacking of private keys on the agenda, but of course there could also be an attack on mining.
Two more comments on this:
If an attacker is the only one with quantum and the difficulty is increased, the attacker does not lose his advantage. It is only slightly weakened. The difficulty also increases for the rest of the network. I also find it a little difficult to see this as an attack at all.
If an attacker manipulates the blockchain with quanta, you're right of course, they're cutting themselves off. But this could also be intentional if a state, a powerful company, a mad scientist or aliens simply want to destroy Bitcoin.
Since AI changes everything, AI could of course also help to significantly accelerate the speed at which quantum computers are developed.
Overall though, thank you very much. Now I can at least look forward to the next Halving with confidence 👍

@DonkeyInvestor Thank you 🫶
Yes, I also thought for a long time about whether I should include mining at all. But I've already received two questions here about whether a quantum computer could simply take over mining - as you say, it doesn't necessarily have to be an attack in that sense - market participants who have access to this technology first would just have a clear efficiency advantage.
You are absolutely right about the difficulty - the advantage would still be there in principle - but the "attacker" would take considerably longer with a 51% attack, for example, or it would be more difficult and cost-intensive to maintain the attack over a longer period of time :)
Yes, AI will certainly have a finger in the pie in the next few years. Nevertheless, I think it will be a gradual process in which the danger gradually increases. And then I'm sure that an update to quantum-safe addresses will follow in due course.
