its acctualy .5BTC and as of today you have to find a block for that to happen. Which you never know when that happens. THE "POOL" THAT FINDS THAT BLOCK, one of the members from there will win the jackpot.
Remember a block is 50+ BTC
Exactly. Let's make it very simple. The pool has only 3 miners, one contributes 80% of all hashes, the other two contribute 10% each. That means divided fairly the first miner would get 40 BC, the other two would get 5 each. However you are not dividing the full 50 BC, you are dividing only 49.5, 0.5 going into the jackpot. The hard worker is unlikely to win this as he is outnumbered by the other two. So you are effectively taking BC away from the deserving and handing them out to casual holiday miners, which was my entire point all along.
