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.
We have to consider the top ranks altcoins upon choosing for long-term investment. They have already been tested and those who are here during the 2018 bear season witness how these coins suffered a strong decline but still survive. Now, as we are in the bear market situation again, investing with these coins gives us some ease and less worries for the future as we already know that they still exist and bounce back when this is over.
Of course, I take ETH as my first option.
