The hype generated by a burn of a big part of the supply will be huge. Let's keep this secret weapon for a while and use it after the bitcoin all time highs are clearly behind us.
News in the bull market are 100 times more effective than news in the bear.
Personally, I think a burn without proper explanation and fanfare will get zero attention. And if we can't even explain and popularize what we've already got, how are we going to do that with a burn?
If you wait a few months and we really are in a bull run, a simple twitter/telegram announcement will allow word of mouth to spread.
We have also made a lot of press releases in the past regarding the fork situation, so the media contacts don't go away and will definitely want to report this.
It is a simple and effective message.
With everyone giving a premium to inflation, just about everywhere you look it looks like the markets reward it anyway, I have my doubts about whether anyone would really care when all is said and done. IDK, but that's my read.
