As for zkSync Era and other ones like Linea, Base, Venom, Fuel, Starknet, etc., I am still betting on it knowing that these big projects are just playing mind games to test us and will be dropping a big surprise in the future.
Well they could be but meanwhile Jito out of blue giving $10k bare minimum airdrop is quite a feel, let's see how projects you mentioned give airdrop or not and if they do, how much.
The rise of Solana ecosystem makes me believe it is indeed a real challenger to Ethereum, with all that has been written about it. I think the team just realised their mistakes and are trying to rectify it, you need to make your community rich, not all these big VCs that do not use your platform, this is what helps Ethereum, with the airdrops, it is going to encourage a lot of people to shift to the ecosystem. Happy for the Solana devs
One good thing about solana is transactions are cheap compared to ethereum, plus I don't think it's team rectifying mistakes as it's projects built on Solana giving airdrops not or Solana itself, but yea if you mean Solana devs making platform welcoming for projects to come in, that I agree.
