TBH, I don't know how Ethereum will solve this high gas fees problem, and to my surprise, there are still many new projects that are being created under Ethereum, and I don't know the reason why.
Project built on Ethereum nowadays simply lets you know that it is backed by more competent and serious teams, Devs and joint venture partnerships, most of them ends up been a very good project with higher value and brings newest innovations in the space thereby making their investors trust in them especially during funds raising. It's a good one to consider project in eth although the bigger boys I mean the whales can only participate because they could afford to pay for transactions fee.
