Be careful investing in minerone.
They screwed early investors by setting coin price in ETH.

A lot of people got in at 0.52EUR/MIO
and today the price is 0.29EUR/MIO

They banned everyone that complained in Telegram Chat.
Every message of people complaining about this was deleted.

Their admin team is very unprofessional. I do not recommend investing.

IceRockMining and Ambit mining tied their coin to EUR making it safer investment.
