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
This is my advice as well.
Don't get into an exchange that is not popular and proven to be trustworthy. Meanwhile, Tezos is the most liked staking coin so far by most exchanges. There is also a new update from ledger wallet that they are also allowing staking tezos on their wallet.
