I wonder for how long you normally hold your tokens purchased in newly held ICO? It's not about your long-term investment into the ICO, but rather about your short-term investment made to make some easy money at the early stage of crypto's life.
I think you need to hold for 6 months to 1 year to get the best price. As per my observation about the ico prices in the first 3 months the price will go down as some will dumps their bounty token and it needs another 3 months to pump to next level.
