You could care less that you are taking coins from other people who are going to get screwed over eventually, good for you.
Absolutely correct ... If it is a ponzi, then they are going to get screwed over whether I'm in there or not.
I've had several contacts with CryptoDouble and they continually tell me that they are not a scam and are honestly doubling the value of invested coin in 100 hours.
Do I believe that ? Well, frankly the jury is still out on that one, but in the mean time I'm going to take it at face value and make hay while the sun shines

Edit: Just checked and so far 9506 investments have been made and 3172 payouts too.
