A lot has been said about IEO. Many seeing IEO as a way out in cryptocurreny, hmmmm..... is that it? don't be fooled. Many of the so-called big exchange have enriched themselves through IEO. Why do you think some projects from nowhere conducted their IEO on these so-called big exchange, it will shock you to know that a reasonable amount of these tokens are going to the exchange and the exchange is ready to dump on you the moment the token is listed or after some pump. They encourage you to hodl but they will not hodl. It is all about pump and dump. You may want to argue because you have benefited one out of many times. Have you asked yourself, how many were able to buy at IEO, they want you to come and buy on the exchange after making it look like a sold out, why sold so little at IEO when you have buck of it in store? Professional scam.....Believe me, there is more to IEO on big exchange than you can imagine. Be wise.
When you say IEO is "professional scam", I will only agree with you for exchanges which lie about the status of the token sale, some will say the tokens sold out while it barely hit softcap and this will create FOMO. Hence when trading begins, traders will set huge buy orders, and the exchange will take advantage to sell the remaining bulk of the tokens. I still believe there are some genuine exchanges, which won't toil with their reputation.
