I started Cloud mining a few years back when bitcoin wasn't too popular. I was using genesis mining. At the time my contract with them got really unprofitable that genesis ended my contract. I was really happy with the company. In December 2017 I joined Hashflare. I was going to buy around 2Th with my debit card but for some reason it didn't not work. At the end I used my bitcoins and had to buy less because I didn't have that much in bitcoins. Anyway right now I am doing pretty good I am reinvesting my money into it so I can make more money on the long end. If you would like to give Hashflare a try then here is my referral link https://hashflare.io/r/5FD37FF6 Hashflare and genesis mining is the only 2 cloud mining services I believe is legit. Genesis mining is actually out of contracts right now and hashflare is pretty good option.
