Where do you stake?
I prefer staking BNB on binance, which means staking at exchange is my option.
Exchanges are meant for trading only, if you are going to use them for staking then you are in risk of losing funds.
Youre wrong at this point, theres a lot of exhange that give you bonuses or rewards for staking specific coins at their platform. And if staking at exchanges means a risk of losing funds, then theres also risk for trading there. Risk can be found if theres a risky situation made by the exchange. Ex : Th exchange has bad issues regarding trust. Theres few of them, but issue stays issue. But regarding funds, issue needs to be taken seriously.
you do wrong comparison, the comparison must be staking in exchange AND staking in wallet. NOT staking in exchange AND trading.
of course staking in wallet is safer than staking in exchange. many exchanges already being scam and stole investor money. the last incident was IDAX and upbit
Centralized exchange is very risky to safe our money, they can be scam anytime
