This may be a dumb question, but on the Block Statistics page, it says that 550 Bitcoins "Need Confirmation"?
I'm not sure what's involved in confirming bitcoins, but doesn't that seem high?
After a block has been found, Bitcoin waits until 120 more blocks have been found until the 50 BTC from that block are being able to be moved.
550/50 = 11 blocks have currently less than 120 blocks after them, so the money there cannot be paid out yet (if you donate 2,5% or more, eleutheria probably gives you a "loan" from his own pocket, until the 50 BTC from that block have been confirmed so you can already pay out directly after a block was found)
