I think also sadly one single entity can always get greedy and turn the business into a scam. I keep it smart. I have a lot of Bitcoin in their system however I compound 30% (reinvest) and withdraw 70% each month meaning in 6 months or so I would at least have 50% or more of my input back. This will always reduce the pain if they are a scam. I have been in it a month and a half as of now. If they was a complete scam I would of expected them to crash and burn a few years ago. I would also logically expect more articles saying they are a scam. There are a few but from past failings, I have checked out their mining pool and a friend knows someone who works there.
