It`s not a scam! DashMiner is a good service.
But with bad miner!
We can't use custom build miners which gives 50% hashrate over their!
Who said it is 50% faster? I wish it was true...
But anyways, this is your choice - I have no problem with people who earn less but use other miners. And please don't forget that pools and multipools also take fees from your mining income.
If you ever want to have a stable income in DASH/BTC, please try our pool...
Thanks
