I have a few contracts with genesis mining.... the main being a dash mining contract. I have had no issues. There has been a couple of instances of late and missed payments but they have always been rectified with no fuss.... i am relatively new to the crypto revolution and found it easy enough to invest. I'm not clued up enough to know whether it was a sound investment but the payments keep coming so I'm satisfied enough to say that it wasn't an overall horrid decision.
