As you can see all these staking are from top exchanges, my advice is to stay away from low rated exchanges that offers staking service, very soon they will claim to offer same service as well, if you have something else to add on the list pls do
If you are an old member or someone who has known about cryptocurrency as a whole you will be avoid it. You will only trust to the reputable exchange although they ask you with the high fee. But for those who didn't know or just new to this market they will find a service which ask a lower fee and entice with another advantage when they use the service.
But if you can have your own wallet inside your own device why would you bother to use exchange service. Not against those reputable exchange but even they have an established reputations there's still chances that you can be hacked not the site itself but your account. Hackers always have an eye inside every exchange if they seen that there's a huge amount of assets inside certain wallets they will do everything to penetrate and sucked everything. be very careful with your venue of investment.
