For me the best altcoin to invest is ETH and BNB. Both of them are my priorities in this year. I don't look at other altcoins at the moment.
for market growth now I also believe in ethereum. I have a few though not many. but the BNB moves quickly, I have a hard time predicting the price. especially with binary events that make growth fast and unstable. because some corrections we can see happen quickly too.
