Genesis Mining has stop responding to trouble tickets. I bought a Monero contract over 2 months ago. I have not received a payout as of this post.
  I submitted a trouble ticket 2 months ago and numerous trouble tickets since. They are all just consolidated into the original ticket and ignored.

So, to answer your question... NO. I do not trust them for Bitcoin mining.

I don't know what their deal is. Maybe preparing for an exit scam. They have pre-sold a lot of mining power, yet to be delivered.
