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.
I don't really think you investing in an IEO project strongly guarantee that the coin or tokens will be automatically listed. There are no specific differences between ICO and IEO. IEO is just rebranding of ICO to bring back investors into investing in new crypto projects. I don't really think IEO is much effective compared to ICO.
Almost all but there are some IEOs are not yet getting listed instantly to the exchange site. but the IEO gives more guarantee for investors to see the coin that they have been invested in to be listed with the more chance compared with non IEO or i can call that as a usual ICO.
