For people who don't understand why this can't last 3 weeks let me put it this way. if on day one, 0.5 btc is deposited it will need .27 btc investment a day later to sustain the payouts, .4158 the second day, then .64, .98, and compounding it would require 113 btc a day by the end of the second week.  Basically the deposits need to go up by 50% a day in order for it to continue. That's impossible for more than a couple days.
