Feedback on my ETF and portfolio weighting

Hi guys, I've been a silent reader of many posts and discussions so far and thought I'd join in, because what better way to get feedback than to take opinions from strangers on the internet to heart?

About me:

I am 24 years old and come from Switzerland. I currently work in auditing and study business administration part-time. I started investing in March of this year. I would like to tell you that I thought about and defined an investment strategy BEFORE I started investing.

At the beginning, I mainly focused on individual stocks such as $ADBE (+4,53 %) , $SPOT (+11,28 %) ,$ENR (+5,94 %) and $IFX (+2,82 %) (which have performed well so far). Now I've realized that an ETF strategy is more sustainable than holding a lot of individual stocks, as I can't possibly keep up with every single company on a regular basis (annual reports, trends, etc.).

I started investing in ETFs with findependent (a Swiss broker). This broker buys ETFs automatically, with the advantage that you don't have to choose the ETFs yourself. Unfortunately, I noticed that the broker invested in 10 different ETFs, which I think is too much for a portfolio size of less than 15k, as I also hold other positions such as individual stocks.

So I am now reallocating and have found the following interesting ETFs at my neobank which I plan to invest in as follows:

$CSSX5E (-1,93 %) 150 per month

$XDPU (-0,02 %) 150 per month

$VWRL (-0,56 %) 200 per month

I mainly plan a growth strategy, but hold 1-2 shares for the dividends. I plan a long-term investment of the products and don't think much of short-term gambles.

I will sell some individual stocks and put them into ETFs, I am still considering how heavily the ETFs and individual stocks are weighted overall in the portfolio, as I also hold a little $BTC (-0,66 %) and alternative investments (whisky and LEGO). Does anyone have any tips on how I can define a sensible weighting?

Many thanks in advance for (critical) feedback :)
