Hi, I have 2 questions
1- Since about a week ago I can't mine sumo, error message says sumo changed algo, use xmr ver 2.*
Is there any way to use claymore's like before?
2- I have no problem with dev fee, so how to enable it or donate to claymore?
Unfortunately no, Unless Claymore revised his miner to support Cryptonight-Heavy Algo you cant mine Sumo with it.
my advise, use other miner out there
