for the next bitcoin halving

You are welcome, First of all i would like to tell you to think thrice before invest. Since you are much younger then you have to wait for gather more experience. But since Long Tram Investment is mentioned, it is a good decision. Initially I think the first 10 coins are suitable according to the ranking including Bitcoin, Etherium, BNB and Solana.
