My question is cloud mining possible? I found hashflare.io seems to be a legit company only here on bitcointalk. I want to invest all of my bitcoins in mining industry and make a good return
Don't dream about making good return with cloud mining, you have to wait for many years to get back what you have spend there. Not only cloud mining, if you don't have cheap electricity in your area leave dream of bitcoin mining, it is not profitable at current difficulty.
