I am not a Gavin fan, but the best thing he did... When he was still Lead Developer... was to warn people against all Cloud mining services. Yes, you might reach ROI or you might even make a profit,
BUT at whose expense? The people coming in after you will pay for that profit and someone will be left crying. Ask yourself this question.. Why would someone sell hash power, if they could just use it
on their own and mine for their own profits?
Well they stated they earn also by trading and mining in bitcoin and altcoins. While I don't believe they only mine, they are operating for 2 years+ now. Doing something good...
