is it better to transfer your token to an exchange once it's listed or just hodl and wait for it to pump?
the question is not clear
but the theme is holding or specuating right?
I suppose you have bought some xxxxx ICO's tokens right?
it depends from the tokens you have picked, but I woud suggest u...never sell anything!
It is one of the few things I have learnt in crypto
Identify projects for the long therm and hold them
it's very important select an ICO or a token with solid basis and hold it because crypto market is too volatile and often people ends with loosing part of the money invested selling quickly the tokens on exchanges. Holding for the long run helps to consoldate the cryptomarket in general.
