All Cardano staking calculators can give you only a rough estimate on how much ADA you can earn daily, monthly and yearly — by staking it.
It depends on many factors based on the Cardano blockchain protocol called Ouroboros, so you will see a small difference in the estimates when using different calculators.
The most used one is the Cardano staking calculator on the Cardano.org website.
One of the long time questions was when will Coinbase add Cardano.
Well they finally did.
As we are seeing an increase recently in people moving their assets to exchanges, and supporting Tezos (XTZ) staking on its platform, I am sure we are going to see Cardano staking on all exchanges soon.
Binance offers 5–9% annual return rate on ADA staking.
But there’s an old saying “If you don’t own the private keys to your coins, you don’t own them”.
