IEOs are becoming a threat to those who rely on choosing project from any exchanges,low rated exchanges have already joined the IEO rollercoaster and projects funds are been raised through these low rated exchanges which to me is a very dangerous risks for anyone who invest in projects from low rated exchanges or even new exchanges.
Do not forget that many new projects are coming into crypto space focusing only on the funds they will raised through IEO/ICO
So what's the solution for this new and low rated exchanges? Of course new projects will choose this exchanges because they are still needing funds. So the cheaper the exchange to start their IEO is much better than taking risks on high rated and expensive exchanges.
