It is very hard to trade with tokens which were not listed yet on any exchange. Most of them dump 10x or more after the first exchange listing.
Maybe you can try with this guy:
https://bitcointalk.org/index.php?action=profile;u=721115 I remember, He had previously offering to buy up tokens from the bounty hunter much before tokens going to exchange.
It should not be the case here though, it's an exchange coin, it has a use case. The only ones that could dump it are the bounty hunters who don't represent the majority of the holders and in that case, the damage won't be that significant.
As for the guy you mentioned, I rather not contact him because his trust already says it all.
The tokens are still for sale, and as I said, I'm not promising any guaranteed gains here, please do your own research before buying from me.
