Maybe it's gonna be cardano, it's growing very fast, but polkadot also can become the next Ethereum, since ethereal is just 2nd coin the market cap isn't that too far and there is possibility for it to be overtaken by other coins but the coins below ETH also keep changing its position so much.
It's 3 candidates, BNB, Cardano, or Polkadot, I think these three the only coins that have potential to replace ETH in the future.
I am agreed with what your opinion, i keep an eye on cardano and BNB especially, i see huge amount of holders on that two candidates, i hope it will blow this year when we see Bitcoin at $100k level.
What do you think Cardano and BNB price at this end of year ? Tell us if you were have opinion about that mate, all you said will be add to my reference.
