Any project that goes straight into IEO does not organize bounty, because the marketing needed would have been done on exchange, which means that doing bounty will no more be necessary. Although, there are few of them the conduct bounty, but planning for an IEO in future. A typical example is Xcrypt.
Yes, and you gave a very precise example, I am very happy to have also participated in the gift xcrypt because the IEO in the first phase was sold out, so for the second phase of the IEO it would be possible to sell everything too, so this made the participants happy and happy.
