If you are targeting long-term investment then make sure you choose BTC, ETH and BNB, the three altcoins that are worth holding until the halving term, I don't dare to suggest other altcoins even though they have potential for this year, but it will be risky if holding them in the next 2 years.
All investments are at risk, even property investments. For crypto because at the moment If you remember Luna Terra's stable project she was also destroyed due to her algorithmic failure, then the Squid Game token was taken away.
As for BTC and ETH I've known them from the beginning. These two coins are the most surviving coins. Holding them is the best potential back to the best price even I think they will exceed yesterday's ATH. Whereas their BNB hasn't been long, but so far they are very strong and a lot of innovations. So owning BNB I think is quite promising.
