I think that everybody chooses something according to his tastes and needs. For example, small investors are likely to choose Binance Smart Chain with cheap transactions. Those who are crazy about NFTs are likely to choose Polygon as it is one of the leading platforms in this sphere now. Ethereum is for whales now, but I hope that with the launch of Ethereum 2.0. will become more affordable.
In general, the fees on the Ethereum network are very affordable, although they are still more expensive than the fees on the Binance and Polygon networks, but in terms of the price of Ethereum which is already very expensive as it is today, the amount of transaction fees that must be incurred by people who make transactions is also affordable and not so expensive, I think so.
