It does seem from the layout of certain things related to the website that the same scammers are operating this too.
Having said that was there ever concrete evidence of maticbit.com being operated by the p2pb2b/coinsbit/whitebit/extrates scammers?
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.
