Yes, I think you've got it right.
In a nutshell:
There will be 12 bounties, one released each day from December 25th to January 5th. Any confirmed claimed of those bounties counts as ONE qualification for the FINAL wheel spins on January 6th. 5 names will be randomly drawn using a wheel spin, these winners will collect 0.005 BTC each.
During the 12 days, 5 of the bounties will ALSO be DAILY bounties, in which any qualifiers will also participate in a wheel spin the day after the bounty period. If there is only one bounty claimant for one of the daily bounties, no spin, they are the winner.
It is always nice to see more earning opportunities. The terms of these bounties sure are confusing but now that you made them clearer, more players would be able to follow them.
However, I'm still unclear about the daily bounty and how the winner is chosen. As I understand it, the daily bounties aim is to round up 1 winner which will be selected on the 6th of Jan (that's 1 day after the bounty period ends), if there's more than 1 claimant then no spin but if more than there's a wheel spin to draw the winner? Right?
