Wrong, bitvavo offer staking program.
Staking Rewards
Bitvavo enables you to earn a return on your digital assets. Our staking service offers a yield of up to 8% on staked assets.
If you scared of FTX or Mt.Gox history, why it bothers you when you only use the exchange for trading? You deposit from your wallet to the exchange with high priority speed, your transaction will be included on the next block and your coins will arrive around 5-10 minutes. Then you sell your coins with the current rate and withdraw it into your wallet, maybe it takes 5-10 minutes. In short you just need to spend around 20 minutes, I don't think the exchange will get hacked during your trade.
If you worried the CEX will freeze your coins, just switch to DEX.
There's no rule to prevent CEX to not offer staking program, lending, or anything related to make more money.
