My main question is: Is it allowed to run a contest or prediction here on Bitcointalk about when mixers will be allowed again? (The contest will not mention any website of mixer)
A policy prediction market, I like it! That's fine.
Note however that I may
soften the ban over time, in two or more phases. For example, I may remove the wordfilter much sooner than any other aspects of the ban.
A step in the right direction. This will be a great year for bitcoin and as well as the bitcoin community.
1st phase: Remove the worldfilter which may happen sooner.
2nd phase: Allow mixers to create ANN threads again.
3rd phase: Approve mixer promotion/campaigns.
Cheers!
