Review by simon avici on Miningcity

This is a ponzi scheme and Sooner or later it will be down please stay away of it to not regret in future.
if you want an evidence:
think about how many investor till now and think how that all of this hashrates and didn't soldout. may be they had purchased all of the mining machines in the world.
please be smart and stay safe.
It’s just made out of copied code and will pump and dump then fade out to oblivion. Here’s a rule of thumb for you, if it has the word Bitcoin on it’s name but isn’t really Bitcoin, it’s most probably a scam.
