Staking has its risks mate if that project value goes down it will affect your rewards, if you can only stake the project on a exchange anything can happen to the exchange, don't ever believe that there is no risk involved in staking coins if anyone told you otherwise you've been lied to.
Staking valuable coin on reputable exchange is a little secured. Not all exchanges has what it takes to run that kind of program so we need to be careful. Usually it is better staking on the binance platform, I have a little above average confidence dealing with binance anyway.
