ETH 2.0 is around of conner with ETA PoS around August or September. So I said right now, ETH has more chance to increase its price than BNB in the future. Don't get me wrong, I like both ETH and BNB too and of course, know how much the transaction fee cost between ETH and BNB. But for the short-term potential of high profit, ETH is better than BNB right now.
Because of low transaction fee, you think ETH has more chance to increase than BNB, I do not think so, what I think is that the more the marketcap the less the volatility. The marketcap of ETH is almost 10x of BNB.
Among other cooms, Bitcoin, BNB and ETH are my personal choice. If we'll look at the price history of BNB and ETH, we could see how they developed and reached a good potential. ETH network is already fixing and developing its gas fee issues so I believe that it's worth buying it during this market situation.
Do you use ETH for daily transaction? The fee can be reduced, but that doe not mean you can not still make use of low fee when mempool is not congested.
