There are two main assertions against keeping coins/tokens on an exchange:
If the exchange goes down like Mt Gox, you could lose everything. Sure, they would lose their reputation but it has happened...
First and foremost, the idea for me is that people think, for reasons that are illogical, that exchanges can act like wallet. I've heard things like this regularly:
"I keep them on Bittrex!" NO! Bad investor..
Or, for new people just buying a shinny new cryptocoin for the first time, they go "Can't I just leave it in Bitfinex?"
NO!! Dangerous choice!
Also, some coins/tokens provide dividends, and some exchanges don't give you those shares; Bittrex didn't give GAS to NEO holders for a long time, and they must've benefited to the tune of $millions, essentially stealing from their clients.
Don't take my word for it, read the articles that I have posted.
