After the end of ico and when the tokens are listed on an exchange, no one can predict whether the price will rise or fall, but in the long run, the value of the tokens, the entire project, can only grow.
In short term, anything could happen. But in long run, everything will depend upon the project's progress.
I'm just sure that due to the large bonuses at the beginning of sales, immediately after the end of the ICO and exit to the exchange, the token will lose very much in price. therefore, it is necessary to consider this project only as a long-term investment!
