3. P2PB2B.io is another cryptocurrency exchange with a dubious reputation on Bitcointalk. In December 2019, BitcoiNaked accused them of scamming him for $3.000 worth of XTZ coins. The user says he wanted to participate in an IEO on their exchange. But that IEO got cancelled, and when he attempted to withdraw his funds, the exchange refused to authorise the withdrawal because of "suspicious activity". The exchange responded, saying that an error is the reason why BitcoiNaked hasn't received his money, and he should try again. They also made irrelevant comments about him changing his Bitcointalk password recently and being an account seller. After 3 weeks, the user finally got his Tezos coins and was able to withdraw them.So i finally received my funds into my wallet, i do feel like i had to go through so many steps and accusations to get my money. Nontheless fair play to them to deposit my money. I can't say now that i have been scammed since they returned my money, so for me now they seem incompetent, since a withdrawal for me took 3 weeks and tons of running after my funds to get a withdrawal.
https://bitcointalk.org/index.php?topic=5207571.msg53283849#msg53283849 This exchange has one positive solved case while at the same time they have many open accusations because of a very shady way of doing business. No matter of one solved case, they can hardly be placed in any positive context.
interesting topic, I hope there will be more positive cases here because trust in all exchanges has been shaken considerably.
