P2PB2B is the most shitty exchanger I have ever seen in my life. They have many problems like low volume, low buy order, fake volume, fake pumping, bot trading. For all this fake facilities most of the scam projects and shitty projects choose P2PB2B to list their token. Also, the listing fee makes the decision here. Thier IEO listing fee is lower than other well known exchanger fee. That's why most of the IEO listed on P2PB2B.
