#1 Way to Tell a Cloud Mining Scam Site
If it looks like this, it's fake:

Before allowing you to withdraw, the site will request a deposit for "verification," "maintenance fee" or some other such nonsense. If you send that deposit, kiss your coin goodbye. Note that the page clearly states that the minimum threshold for withdrawal is 0.00006 BTC. Yet, when you click withdraw, it says the minimum is 0.005 BTC. The upgrade packages are also outrageously unrealistic. V4 on this particular site costs 4.99 BTC and promises mining profit of over 1 BTC/day. I'm sorry, but that's just not going to happen. 17 million of the total possible 21 million BTC that will ever exist have already been mined and, if this site were legit, the remaining 4 million would be mined well over 100 years ahead of schedule. I have come across dozens of sites that look exactly like this, but under different names, with slightly different speeds and package prices, but the fact is they are all fake. If you know anyone who is new to cloud mining, make sure you share this information with them. Any legitimate cloud mining site will have maintenance fees that are deducted directly from what you mine. Any "pay to get paid" model is a scam, period.
