When was the last time you have check Ethereum fee prices? They are 3 times less than they were month ago. And I suppose the will be getting even lower. What was the main reason people paid so much attention to BSC? Ethereum high fees. You can now make a transaction on Ethereum blockchain for 45 gwei ($2.4). What are BSC network fees right now ? Cant give that info instantly, but they are not so low to make BNB replace Ethereum.
It feels like we live in different worlds. At the time of this writing (04/27/2021), the commission on the Ethereum network is $ 10. This is a very high value. Again, as of today, sending 1 BNB on the BSC cost me 10 cents. 10 cents and 10 dollars, as for me, the numbers are much more indicative than any words.
P.s. Ethereum - lost this battle, in my opinion.
