I don't think there was a bounty campaign. This dump was carried out by holders who obtained tokens at minimal prices at Crex24 or perhaps someone on the team. Either way, it's hard to know.
That should let the members here who usually blame it on bounty hunters believe what we say that bounty hunters share of the tokens cannot affect the price of the coin even if they all decide to dump the coins once on an exchange but rather, it is from seed round buyers who bought with as high as 200% bonus and team members that dump the tokens
