Hey there!
I have around $26k in stable coins, and currently own:
If you haven't invested yet, here is my advice. The most trusted currency is Bitcoin so you invest 50% of your amount in Bitcoin. The most trusted currency of altcoins is ethereum so you invest 20% in ethereum and you invest 10% in solana and 10% in BNB coin and 5% in MATIC coin. The remaining 5% can be invested in some good coins in the crypto market. Many others have advised you here, you can invest according to the advice you think is good.
Your suggestions are good because you have suggested the top cryptocurrencies based on performance and almost all of them gained value when bitcoin went up and created a new all-time high whereas a lot of altcoins didn't manage to gain much value.
However, I wouldn't suggest someone to invest everything they have in one go and they should always have something left behind because the market is highly unpredictable, and in case it goes down again, there should be liquid assets that they can use to buy more assets at lower prices than the current ones. So, the best way to go about it is to DCA into all the cryptocurrencies that one wishes to buy and keep doing that in case the market dips from the first buying point.
