well the best altcoin to buy is right now is etherium
becuase market is way too volatile right now due bitcoin having a very deep loss from 50 k to 28 k in few weeks
and lots of coins have been also down like luna coin which made lot of people cry so i think etherium is very good coin to buy right now
well you can also buy bnb coin.
Yes bro eth has potential to skyrocket and also volatile. It also merge from PoS to PoW it is a great step I think its will be pump but wait for Market good
