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.
