regarding 8/ (in brief wrong wrong wrong) at Jackpot attribution a solo miner doesn't have any chance at all to hit it (yes yes it is random but already picking any block is difficult, picking the one with the jackpot is close to impossible) and reality so far has proven that this comment was wrong it is always a pool which get it, and worst it is always the largest pool which gets the jackpot....
There was a week ago a discussion regarding a jackpot attribution through minting, did it go anywhere ? This would be truly random with no bias at all (and I wonder we want to reserve the jackpot to those who already get all the coins... )
The real force of jacpot coin (and I release that only recently) is the fast decrease of the POW reward and this might bring the price to the roof.
