I think that the listing will be waiting for all investors who did not manage to allocate $ 1,000 for the purchase of tokens during the ICO.

But not the fact that they will be able to buy tokens at a nominal price. I think investors will not rush to sell, expecting natural growth.
Many say that investors do not sell their assets on an exchange. However, in most cases, as soon as some asset begins to be traded, the price begins to fall.
In such cases, the culpable angel investors, who bought tokens with significant discounts and dumped prices on crypto exchanges.
I'm not sure how the price will change after ICO, but adding tokens to the exchange will inevitably entail a change in course.
This is a familiar pattern. And we will not affect it in any way. Therefore, investors need to decide for themselves when it is profitable for them to buy project tokens: before listing or after listing?
This question more and more often makes us think about what is more profitable. In the case when the token is from a promising project, it will be supported by the teams work further, then there is a chance for growth after the listing.
