now i'm making $28-30 a day with 800MH in eth, is there any coin alternative that would be more profitable?
It depends on your video cards. If you have Nvidia 1060-1080 or AMD 470-580 video cards, then it’s easier for you to continue mining Ethereum. If you have modern video cards, then study the information about dual mining Ethereum+Ton and Ethereum+Alephium.
LHR cards are good for dual mining Ethereum+Alephium it's like using a complete non LHR card for mining so go for it if that's what you have, as for most cards ETH mining is the most profitable.
I tried eth + toncoin and it gives 12 ghs per ton coins, which saves only $2.8. Is it worth pushing my graphics cards?
