Is your investment amount in BTC? If so, is 1 BTC invested with ROI of 2.95%, a profit of 2.95% in total? The amount of days, is that how long it took you to get ROI? How profitable are these contracts...I was thinking of starting one.
Have you ever just purchased a miner on hashnest instead? I really want to try mining again, but am super weary of not breaking even.
Cloud mining doesn't worth. I think it's impossible to mine the same amount of BTC you invested. The only way to make profit with this kind of investment is when the BTC price increases a lot meanwhile your coins are invested on cloud mining. This way you hit ROI and make some profit.
But what people don't say is that you can make a better profit just holding BTCs instead investing on this kind of site. If I'm wrong, please correct me.
