i think they have another chance to claim their btx ,but only 40% . the plan still not talk about the final airdrop.
Yes, there is still no information on the scheme of the final airdrop.
If you just read the announcement carefully all the information is there. There will not be a final airdrop in november. The 3% will continue untill all the unclaimed coins from the orginal snapshot have been distributed. But not including the 7 million that will be sent to every bitcoin adress in november for the new snapshot. This is really a great solution and vastly increases the chance of real adoption.
