Coinbase offers "Cosmos" with a yearly annual return of 17.66%.
I did some research on Cosmos and its future looks bright.
On my research, it says to only Stake on huge platforms, such as Coinbase.
I realize the drawback is you freeze your funds for a certain amount of time.
The other drawback is because of Crypto's ups and downs, you might lose money if it goes down. But that's true of any crypto, including BTC.

As far as I can tell, the annual return stays at 17.66% for the duration.
Is there any drawback I'm missing?
Why don't people just buy Cryptos that they can stake?
