Sorry I'm new to all this. Can you tell me how to do that please.
Sure, it's simple. If you're on Windows just close Grumpycoin's client, and go to ->>>
C:\Users\USER\AppData\Roaming\GrumpyCoin.
Then just press right clik -> New text Document and name it
grumpycoin.confAnd pase this info in it:
rpcuser=user
rpcpassword=pass
port=55904
rpcport=55903
rpcallowip=127.0.0.1
daemon=1
listen=1
server=1
addnode=162.243.90.199
addnode=201.141.146.117:55904
Now open your Grumpycoin client again and it should sync.
Thank you I will try that.
