even now ethereum gas is still high to make an ERC20 token transaction it takes 12$-30$
this is the problem for ETH blockchains that has not been resolved until now is the high fee even some projects are pending distribution because the fee is too high
We thought that the London hard fork will decrease the fees. But with the looks that we have in the market, there's still not that much effect from that fork.
We have no idea until when we're going to see the fee gets lower.
