Is mining and staking the same thing? How is staking calculated? Do we know how many CRX have been created so far?
Staking is mining. (
https://en.wikipedia.org/wiki/Proof-of-stake)
Staking (POS) is calculated at rate 50% per year. (50 K new coins are generated due to POS mining per day)
50% is for first year. (It will be lowered to 3.5% after 1 year period)
