Right now we have seen many projects that use big exchanges and raise fund easily and their token value tripled up, I'm sure new developers are aware of all these success but still we are seeing new projects using p2pb2b exchange for IEO, it's obvious that they know what they are doing.
For exchanges like p2pb2b or latoken, there is certainly not much hope for investors because the IEO projects there are not liquid and very few investors participate. I think the IEO projects listed there are all bad projects and you will definitely only feel worse when investing. It is best to choose only exchanges like Binance or Huobi to join IEO because these exchanges have great reputation in the market.
