If you want to choose where it is better to invest, then it is best to invest in both cryptocurrencies, since both cryptocurrencies are very popular and therefore it would be reasonable to invest in both cryptocurrencies, and if you want to choose between Ethereum blockchain and BSC, then of course I will choose BSC, because making transactions through BSC is very cheap, but cryptocurrency transactions on the Ethereum blockchain are very expensive and therefore I do not like this blockchain.
