Well In my case, I just hold it up for about 2 weeks to 1 month while checking on the exchange platform about the price of it... In tjis kind of business patient is a virtue... If the ICO is done checl the price of the coin or the token sometimes new coin on tje market are high in value it is around 1- 5$ in value and suddenly falls down to 0.2$, but if tje ICO follows it roadmap and continouosly developing the coin in the near future the price of the coin will increase and you will definitely get high profit on it. Maybe you should need to check once a week the price of the token or coin you hold just for update and reference
