But I see many prize campaigns from the IEO project. One of them is ASTRcoin, and is now listing IEO in the Latoken exchange. But listing exchanges after IEO are not necessarily in LA.
IEO is a marketing strategy for a project to get investment funds from investors. Bounty is a promotional program aimed at hunters with project targets able to achieve a good level of popularity.
A project is not required to create a gift program if they believe the product will sell on the market when sales begin. But there are quite a number of projects that create gift programs with the aim of getting more communities to their products.
Usually every project that carries out IEO on the platform, then they will also release their products there after the sale is complete.
