We have similar integrations coming soon for other large online communities.
Why not airdropping to Facebook users? It's the ultimate online community with 2.2 billion active users.
Providing that 10% users would participate giving 1 MB airdrop to 0.22 billion users would take 220 000 GB.
Because Byteball foundation cares more about wide fairness distribution (well, what they say is fair) rather than fixed and predictable rules.
If it is going to be gamable means it cant be done. Because of that, airdrops to holders (or any other predictable-by-design distribution method) is a good form of distribution (better if it last years). It cant be gamed. And anybody could know how much and when will be the next coin supply increase. Distribution problem solved.
This is what I think: encourage hold until BB reaches a wide userbase. But nobody except two or three slack users agrees with me.
