It would be very interesting to read an article about such a blockchain or more precisely about this kind of earnings if not water in this text, I would like to see some real numbers and not a link to this calculator from which it did not become clearer.
You can refer to the figures right here: https://cardano.org/calculator/?calculator=delegator. This is Cardano's Staking Calculator, everything is very intuitive and clear.
Currently APR ~ 4.6083%. Compared to many other blockchains like Cosmos, this APR is quite low but it will be good for Cardano in the long term and support the ADA token price.

You can also use another website that is quite user-friendly and has more features like https://www.stakingrewards.com/asset/cardano, here, you can choose Provider with different APR.
