Possibly because they have been upfront about the fact that a lot of it has been premixed and how it is going to be distributed amongst others. Airdrop is a good idea and allows people who dont have big rigs to get involved and support something they think can work
Airdrop is indeed a good thing. I wonder why there is so many ICOs when airdrop clearly is a better option in my view. If you got a low supply in your coin, say under 50 million and drop say 10-50% of these over a period, you automatic create interest and you get coins to a lot of people, possible holding or rising the price, by that alone.
If you on top of that actually have a game plan for the coin..... it helps
