Told you guys,
This user is lying about partnering with the Bitcoin.com mining pool so i would assume that the whole setup is a lie.
Someone on DT needs to "tag" the users account as a scammer.
Since you are deeply involved with bitcoin.com(at least the forum side), i'm going to believe you. They did claim that they worked with pools from the likes of btc.top, bitcoin.com all the way to BTCC and bixin:
Ps: We are working with a large group of miners who use btc.top,bitcoin.com bitfury,antpool,BTCC,Bixin and gbminers. We are not directly linked with these pools. If you will submit your tx to us you will know.
I feel like a lot of the transactions are being confirmed using antpool, which means that they COULD potentially be using antpool's free service and charging a fee for accelerating these transactions. Highly shady if that's the case.
