At the time of the listing after the end of ICO, the price often dumps. Why does it happen?
I think the reason is there is no buyer because of no demand for tokens since the ecosystem is not completed after the ICO.
It may be difficult because lack of funds, but I think the team should release a product like Dapps while running ICO to make token demand.
How do you think about it?
First you need to study the altcoin/token to learn whether the valuation is fair or not. If the valuation is fair and even after that it goes down in the market, then I would say that you should hold on to a part of the tokens for at least 6 months.
