I'm not sure but for me, I consider them investing in the short term as these projects seem worth it. But if we look for the long-term, better to stick on BTC and ETH, or just to add BNB on your list as these coins are really proven to be promising.

I have some Solana (only) for the try but I don't hesitate to sell them anytime once their performance isn't good. I was considering them my new investment but for now, it seems working and to profit. However, it was the question of whether this will commence long-term or just end shortly.
