If you guys are feeling that Cryptodouble is getting to (extra) risky, you may like to check out Weeklyponzi.com.
Iv only been using them for about 7 hours now, but I have already been betting with 3 BTC in groups of 0.25. It has only taken about a hour to receive the 130% return. I can not tell you how many times I have reinvested (Honestly no idea), but I am already over 5.8+ BTC at the moment. Its so new that I feel safe to keep this up all night >=)
PS: Watch their deposit address on a explorer for a minute, the volume of deposits are wild right now.

Also playing this the last couple hours... its fun, cause you can see exactly how much more needs to be "invested" to get your own payout.
Its a ponzi, but fun atm
Well the site's owner collects a 5% fee from ever deposit, but that is not taken away from the final return.
You can watch it happen in real time on the Block Explorer.
1 BTC Deposit> 0.05 BTC sent to labeled Fee account > 1.3 BTC Paid out.
So I really do think its going to run until it 'naturally' implodes (4-5 Days). Oppose to the owner running away at any time with the funds.
