The problem with ETH gas fees is making people speculate on other platforms like PolkaDot. But once the ETH 2.0 kicks in, these fees will be burned and it will be a game-changer for ETH and we have to see the competition then. There are already a lot of good projects on the ETH platform and Dot may get some in the future.
I think if the problem is in the transaction fee, BSC has become a solution. the popularity of DOT, which I think is widely discussed and thought to rival ETH. but I believe it is too young for Polkadot to compete with ethereum to make such a claim.
