For one, an identity could not yet be linked to this dev and we know only of his alias in this forum. If there are others working with him, they have not yet been identified. But if one reads about this project from the start, it's easy to see that he's working alone.
Then there's concern that the project doesn't have a reputable escrow. It's just dev that holds the funds and can tamper with reported btc holding using wrong coding or something as an excuse so he had to "correct" the reported btc holding displayed on the ico dashboard.
Bro fuck craig. It's a baseless unproven accusation and doesn't even deserve a response. If I was the dev I wouldn't even reply to that, just focus on advancing the tech. If craig scares you then find another coin.
