Rebranding is a last resort if the token fails to rise, but if POL does not gain traction and popularity in the coming months, Polygon(Matic) will perform poorly during the current bull market.
I doubt if things will ever be the same again
Apparent the Ethereum gas fees have been dropping for a while so there will be no point of these layer 2 in the long run. Moreover, there are also very competitive layer 1 blockchains to Ethereum, such as Solana.
I think L2 has many more uses than just reducing fees. For example, decentralized exchanges, NFTs, games, and many things that are not considered transactions should be there. Here, the fees will be constantly low with the possibility of being able to be scalable in unnecessary directions.
