For now I prefer Binance Smart Chain (BSC), because gas fees from Binance Smart Chain (BSC) are cheaper than Ethereum and transaction speed using Binance Smart Chain (BSC) is also very fast (same as Ethereum), that's why I prefer Binance Smart Chain (BSC) for current transactions, unless the gas fees from Ethereum are back to normal or become low, then I will definitely use Ethereum again, because I'm actually used to transacting using Ethereum network, but because the gas fees from Ethereum is very high for now, therefore I am not using Ethereum for my current transactions anymore and prefer to use Binance Smart Chain (BSC) at this time.
But I think as the market will be in bear season, ETH fees will also have to change and I'd never been hopeless seeing this back again. So if we can see people are currently using BSC just to save the cost but as you have said when the fees back to normal, yeah, these people will get back to ETH. I believe this was the best choice, Ethereum has been proven and trusted for so long, and I think we can't easily give up just because of the fees, coz if we are talking about a long-term investment, ETH is always on the top among altcoins.
ETH platform is definitely one of the solid projects in the crypto space. However, right now, people are going to BSC network because of cheaper fees aside from the fact that it is under Binance platform, which is a reputable and top crypto-exchange. But when ETH gas fees return to normal or at least comparable with BSC, I believe, people will restore their loyalty. Both networks are important and they cater different users, so for me, both are needed in this crypto ecosystem. Both have pros and cons, so it depends on the user how he will use both networks to his advantage.
