All devs info is private, only what I can say - Graffiti dev has not fulfilled the promises given to us on skype, and stops responding immediately after the 4 day holding period. Explorer was not provided (despite the promises), blockchain stucked, no good nodes. This is the main reason why we declined his ICO. Graffiti dev is in black list, if he wants to put a new ICO coin - fee will be 5 BTC (as a guarantee that no more scam will be).
100% buy wall means only one thing, it will be totally eaten, and dev will own 100% of his coin.
Thei didn't answer about graffiti ico and why they refused it.
