I’ve been using NiceHash for a month and they are good. But I’m actually Mining with equipment. However, I’ve also been cloud mining with Genesis Mining since June. For $300 in contracts, I’m making about $28 USD per month. My two asic miners cost me $2000 total. They went from making $110/month at the beginning of October - down to $65/month now, 10/29/17. Also, my ASICS have lost over half their value, so I cannot get my money back by selling them on eBay. So, I’d say you’re better off, at this time, to cloud mine.
