While I do agree with the assessment of most of the post...I'm also inclined to agree with this comment. With the minimal amount of money really invested...you didn't put yourself in the best position to reinvest regularly, which is where the real power comes in.
Not advocating for Hashflare, but I have been with them for almost 4 months. With a decent sized deposit, I made sure I was at least able to auto reinvest daily and now my hashing power is more than doubled. With the increase in pricing aswell, I was able to even cash out my initial investment and just play with "house money".
I do not doubt that you have got your "money" back, and managed to double your GHS. bitcoin has gone up 3-5 times what you paid for it. As far as the difficulty, it is now twice as hard to mine. Much of the argument in the cloud mining debates is if it better to just buy and hodl the bitcoin.
