Scaling for all EVM chains
Well, that seems to be the intent of Elyrium anyway.
Elyrium (LYUM) looks like it might be a good investment medium term at least.
It should enable (infinite?)/scaling on any EVM chain. Awaiting testnet release.
Currently it's in BSC but will be on it's own chain when main net is released. You can buy on MEXC (zero fees at the moment) but a 12% fee to withdraw. When main net up and running I'm tild there will be zero fees.
I guess if you make a small investment you could wait to withdraw, but remember, not your keys, not your crypto so that's the risk you take by leaving on exchange.
