it's a natural thing if the price of the token falls after ico, especially if you start distributing coins to many parties. many people want to get a high price and as a result the price of the coin plunges to the lowest base and has to wait a long time for the coin to reach the highest position.
to date Trust in projects and crypto-currencies has fallen a bit. If you remember the year 2016, then everyone kept the coins after the company's ico to get the highest possible price for the tokens. And to date, most are trying to sell coins after distribution.
they wanna sell immediately because they are not sure with the project. it's normal to avoid lose (down price)
