Some suggestion already suggested for OP but from your post and it looks like that guy was a scammer. The manager was putting the new price 0.007$ as the buyback price for the hunter's token.
he didn't have token and he wants to scam others. he can send it to the team's addreses and got eth as his payment. there's something fishy here.
Same thoughts here mate ,Imagine a Newbie account that will have that Tons of token from Bounty ?How many campaigns has he participated and how many accounts need to accumulate that volume ?
and yeah there are many Buyers of this coin from weeks ago but all of a sudden he comes out couple of days coming from nowhere and offering His tokens.
Maybe he took the advantage of the demand from outside IEO and may try to have a victim using a Newbie account instead of using his main account.
