I am user of minergate since a long time even mine few of coins with minergate. But I realize that minergate supports for cryptonote algorithm based cryptocurrencies.
SO can anyone give me info about external mining hardware work with minergate ?
Don't use minergate.
Why?
Minergate = bytecoin = scam.
Basically, the old timers in monero don't trust anything bytecoin related. And I won't be sympathetic until they come clean with their scam.
For me it's ok, simple to use and transactions don't have any problems. I'm new in monero mining and I don't know what they did before and why it's scam but now it does not have any issues, at least for me.
