It came to me as a surprise! I initially thought IEOs are little more safer than direct ICO route because an exchange is involved in the whole process eeds no matter it is an ICO or an exchange!
the only difference between ICO and IEO is in the order things happen.
in an ICO they first create the shitty token and scam people with it and then attempt at getting it listed on an exchange by paying them so that they could dump it and get the money they scammed out.
but in an IEO they first pay the exchange to list the shitty token then create it and scam people with it while it is being advertised by the exchange. and then they dump it easily and faster since it is already listed on the exchange.
