It makes more sense, to let the top 15k of every country the ability to ask to join the thank-u system, instead of pretending to be able to convince the top 5k worldwide.
Thank you bringing this up, dael. Just checked - bitcointalk.org is not in at 5,116 - no good! : )
Joking aside, anybody has the ability to join thank-u either by generating an account and placing it on their web pages or associating the account with their domain name. The questions is how to distribute the emitted liquidity in a way that is fair, lossless, fraud resistant and attracts early adopters. We design money supply controlling algorithm to distribute or withhold money among the biggest recipients in accordance with their activity. (The platform emits to those who are most likely to be there if/when some of this money would need to be destroyed.) There will be no limiting site lists, once the platform stabilizes but when there is no reliable statistics during warm-up we chose to use a conservative limit for the seed emission to protect against fraud and keep tranche amounts reasonably attractive.
What would be the benefits if we spread the 5M among hundreds of thousands domains? More participants with less chances to win?
