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.
may be because of this many investors are trying to buy tokens after the ico company, rather than invest their funds during ico.
