Well i am glad you are pretty much aware of the risks of taking financial advice from others, but since you already asked, i'd answer based on my own knowledge. If you already have a good amount of Bitcoin, then what you should do is to buy other assets that are not cryptocurrencies, diversification is when you buy Bitcoin and other non-crypto assets. OR you could continue to accumulate more Bitcoin into the long term, there are quite a lot of people that have thousands of Bitcoin, but yet still accumulating, it is a long term sustainable coin and has a very secure network so there's nothing wrong in accumulating as much as possible, as long as you can hodl it safely and prevent loss.
