But by the time this has been attained, the population of bitcoin users would have greatly increased do you think BitcoinTalk Forum will not be jam-packed and will bounty no stop?
Bounties probably will stop during that time because most of the projects that will stay during that time will be the most established. There would be a new gig economy for that but it won't be bounties anymore.
I agree and think this way too, the bounty program is likely to end in the future,
many ICO projects, IEO, STO and gambling sites will become established in the future because of the possibility of mass adoption,
for preparation, I strongly recommend using this time well and learn from now to have a business other than cryptocurrency.
