I think bounty hunters dumping to the buy orders. Cause couple days ago bids around 200 sat now around 110. And nearly 500k sell order at 180 sat.
It is understandable because the bounty hunters have been waiting for so long time to be able to make profit from this project, so it is normal to see the dump moment after there is a way to sell it but I think it will rise again because I'm sure this project is a good long term project.
