This is because there are no investors who want to buy the token of the ICO.
Back then in 2017, there are many investors bought the token, even after the sale reached hardcap.
That's why many hunters received a good amount of reward at that time.
Our current situation is very different than 2017. At the end of 2017, wherever you invest, it would return as profit. To me, pausing good projects is another reason. If you paid attention, it was not difficult to encounter this view when the btc went down.
