my suggestion
you should add % reff

hmmm this stinks of the recently scammed BTCSPROUT which had an extremely similar setup.  Basically, it was 170% in 10 days or whatever and this one is 200% in 10 days they both returned principle on the last day as well.  There is also another program with very similar specs that I just saw that just popped up that does 150% I believe.  All of these programs except BTCSPROUT are started by newbies most likely because chalkboard(admin of BTCSPROUT) does not want to come back online after scamming and no one would trust him again.  My guess is that they are all made by the same person.

Long time with small return. When I gamble on a dice game, I am able get 500% of my initial amount on just two hours
