In my opinion, I think there are three contenders and they are Ethereum, EOS, and BNB.
EOS has no future and Ethereum is a huge risk because of their PoS update. BNB is another story. If Binance will continue to grow then i see this token going much higher.
I sorta agree that ETH took a blow with the PoS upgrade, but I Can't see BNB rising too much, considering Binance has an obsession with power grabs and it's really evident they don't care about their community as much as they make it seem. EOS on the other hand, though it has its flaws, I think it just needs a decent update in the federation method, otherwise it has potential.
