Yes, many projects that have made IEO sales in the various exchanges they choose to attract investors, but in my opinion if you want a lot of investors or interested buyers, you must do the IEO on a well-known stock exchange or top rank because there are always lots of invetsor.
Normal thing to consider when listing or choosing up for an exchange where you should really select the top tier ones.
Its normal for people on eying those popular exchangers rather than into those who are on bottom.They do mostly get the attention
or the hype when theres an IEO project listing/sale.
