be careful, they are scammers.
here are the facts, at least my experience with this scam team.
i invested în rock1 in october 2016 and nothing happend. Then i started to ask what is happening on facebook they didnt answered many months ago then i asked questions on telegram, and i found out that in order to get that mining hash i have to talk with some guy Diias but he is never rechable... and i was kicked out from telegram group rock1 and rock2... so now i WARN people to not lose money.
More that this some russian friend warn me saying that he talked with dias in russian language and he warn me not to invest but i tried with a small amount.
I cant wait for ICO reglementations but this type of guys deserve harsh punishments.
