They are back, this time it's maticBIT (maticbit.com).
Same MO, Discord promo codes, you enter the code and you get BTC "credited", then you have to deposit 0.05BTC to withdraw.


Who is back? How they "maticbit" are related to p2pb2b?
by the second screenshot, it seems they use similar exchange software, but it is not real proof. If you know something more, can you share it with us?
