P2pb2b is home to an ICO or IEO scam, I have experienced it and bought IEO there, and the results are I am losing,
I want to remind you, be careful to choose
Not only this, exmarket and latoken is also the shady and shit exchange for any IEO. I hodl some coins of a project which do their IEO in Latoken and the price of that coins dump around 100x which are now valueless. Besides, withdrawal fee of latoken is so high that i don't reccomend to trade on it. Also same thing happens with exmarkets. So, everyone should stay away from this type of shady exchanges,IMO.
Chainx, probit, upbit .. there are also scam and bad exchanges that need to be added to this list. Stay away from those exchanges to stay safe in this market, and never join their IEO. I am sure the price will collapse and fall many times after being listed
