That's sounds really messy, fees? You're the one that offers a different MM and you want me to pay FEES? Cmon, stop joking with my face, i'm not a rich kid....
I can go lower than 70% yes, but i'll not pay fees or anything.
I can trade directly with users like you with 200~TBM and i prefer that because MM don't get RED NUMBER (negative tbm) and people still thing they don't scamm, like this:
He had 3 bad mediations when he scammed me, now he got 5, and no1 does nothing.
