Weighting of cryptos

Since last year I am in $BTC (+1,14%)
$ETH (-2,56%) and $SOL (+0,84%) and things could hardly have gone much better. In the meantime, cryptocurrencies had a weighting of over 15% in my portfolio.

However, as I'm not that deep into the subject of crypto and don't see investing in cryptocurrencies as being nearly as much of a retirement provision as shares, I decided to take a closer look at how I want to proceed with cryptos, with the following result:

- I would like to keep the weighting of cryptos in my portfolio at around 5%

- The allocation should be 50% if possible $BTC, (+1,14%) 25% $SOL (+0,84%) and 25% $ETH (-2,56%) correspond

- As soon as the weighting of cryptos exceeds the 10% mark, I will rebalance and take profits in my two large ETF positions $5OGU and $IS3R (+0,94%) reallocated

=> With such a weighting, I remain relaxed, buy/sell based on rules and would still benefit from a long-lasting crypto hype. After all, rebalancing after strong price gains in the crypto sector logically increases my overall portfolio value, which means that in absolute terms there is more "space" for crypto assets than before.

What do you think of this weighting strategy? I am grateful for any shared opinions! 🙏🏼
