Now for some small capital users, your income may not even be as expensive as the gas fee on eth, which is obviously not worth it. So as a small fund user, I prefer to use bsc.
with a small capital of course BSC and some tokens on the market on the BSC network will be more friendly. and there are still many tokens that have low value. I am sure you will get a good investment asset. instead of choosing ETH and BTC, it will only kill your assets for transaction fees even if you hold them for a long time.
ETH fees was also cheap back then, it's because the price of ETH is growing so big and also the network is crowd i'm sure that made the gas fee of ETH sometimes more than 70. Which is not really worth it for doing many transactions.
I'm sure when BNB price is high as ETH, there will also fee increase to it. and another competitor will come to compete with them (solana maybe is maybe their competitor in the future).
So as an investors and traders, we should always keep up to date about what is really good and profitable for us on the market.
