Tried Minergate some day. Tried hardcore (lol) pool mining the other day.
When I discovered that my hashrate and the number of earned coins are SUDDENLY quite lower with Minergate, I quit.
So be careful.
Yeah. Minergate is pretty well known for stealing hashes - theres no good reason for it, honestly. Just be warned.
If you really want a one click mining solution just use Nicehash.
I stopped mining there a long time ago, after spotting mods bragging in miner-gate chat how others using miner-gate unknowingly were mining for them. i took several screen shots it and sent to support, they never replied, so who knows how deep it goes, maybe mg is in on it, or told them to hand over the coins to them or else.
