i don't know how to mine this, there is no guide anywhere on the net. Left...
it's no different to any wallet mined coin.
1. download wallet
2. go to C:\Users\\AppData\Roaming\OPES (or whatever that is in your language of choice)
3. open OPES.conf and add:
rpcuser=someusername
rpcpassword=somepassword
rpcallowip=*
rpcport=9999
server=1
4. save config file
5. download miner in OP
6. run cpuminer-win64-generic -a argon2 -o
http://127.0.0.1:9999 -O someusername:somepassword
7. profit?
