maybe ethreum , bnb ,btc will mentioned as good coins to invest right now. this top crypto currency in cmc now and proven as good coins that could survive for long term. if we flashback look it , maybe alot project that start in same time with these coins now dying.
It is very clear now because everyone can see and judge which coins can be suitable for long-term investments because basically everyone has to see how many coins are in circulation every day and how many coin holders are, because with both things it will always be placing coins in a better ranking and it can be seen how much demand there is in the market and the three coins you say for now I think it's still very feasible to be used as a long-term investment because of some of the considerations I said.
