People are very smart and wise now. They are now thinking very carefully before to invest so the chance of being lose is now decreased. I invest on some IEO and now its successful, Now I am waiting to list the token on the exchange. My mind is still worrying if this token will be listed or not.
If you have participated in IEO projects then you don't need to pay much attention to the time listed because you will surely be able to sell that coin in the earliest time. Most of the current IEO projects are profitable for investors but only top exchanges can do this because big exchanges have large amounts of money to pump that coin. I think this is a very effective and smart strategy and choosing a big exchange join IEO is something you should do in the near future.
