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.
For me now, the best way is just to sell 70% of purchased tokens if I see I can make at lest 30-50%
with the rest of them I can hodl in order to achieve another profits, but if I see a project has some problems , I dump the rest immediate !
