Other than Binance, I don't trust IEO from other exchange,
Because in Binance, HYIP is high, you can earn immediately without checking the project. Is that a good thing? It is good at making quick profits, but essentially garbage in investing in the future.
IEO projects on P2PB2B are because they do not have enough funding and do not have the professionalism to get IEO on large exchanges. Large exchanges only support really potential projects and the dev team must have enough talent to develop the best project possible. That's why shit projects often go to P2PB2B or Yobit to get token sale.
The weak projects know that they do not have a chance in the bigger ones and they apply to appropriate exchanges like p2pb2b. p2pb2b charges a fee and the rest is none of its business.
