All the gains with btc were made already if we are looking for 4 years from now is only 2-3x .
ETH I could see 5X in the next 4 years it has lower marketcap and better roi.
I wouldn't bet on metaverse coin yet because all the project look superb. look at sandbox, decentraland is not look like they have bright future too.
Terra luna is intersting decentralized stable coin and this cool project.
eth competitors will faid away when eth 2.0 is arrived. i don't see why anyone would build in solona . recently they just got hacked.
Cardano is hard to develop on there are no need for eth competitors.
I like bnb though i think it has good future its the easiest to develop on regular coins and it's safe.
Good coins are Eth, Terra luna,Bnb
