I think that it is definitely worth buying after a coin or token will be sold on the exchange, since investing in an ICO is very risky.
not all tokens or coins that have been entered at the exchange can have a good price, most nowadays when they enter the place where the price exchange falls and makes many investors lose, different when the project development is good and the team owned is very committed, it will make the price can be expensive.and to have a good value in exchange is really tough at the moment. most of the ico projects failed to achieved their committed price. and for me, if you see a good project, better wait for it to hit in exchanges, you can get them really cheap because of the dumpers. believe me.
