Every advantage has its disadvantage, and so does Staking. Cryptocurrencies can be very volatile. Sometimes more so than the interest you receive on them. The higher the interest rate, the more volatile a coin usually is.
It is also normally the case that you have to hold your coins for a certain period of time. During that period, you can't trade them, but with the BLOX app you don't have that problem, fortunately.
You can take your coins off Staking at any time - unlike many other parties - and then trade with them. Any crypto you deploy for Staking remains yours, but you must 'unstake' it before you can trade it.
