Just find a good exchange and this is it. Unfortunately, it does not matter at all how good the project is, because if the IEO is held by Binance, every single token is going to be paid. Take part in IEOs on top 5 exchanges, and you won't manage loses at all.
Agree with you, I think we should choose the big exchange floors to buy and sold crypto due to the high security and avoid losing the information of wallet. IEO is the non-potential for us to trading. If you hold ICO token, please change To the BTC or ETH to make transition
