How much is APR for staking now?
20% Inflation Per Year.The amount of XBC coins that are 'minted' each year is 20%. This means if there are currently 100,000 coins, in 1 years time there will be around 120,000 coins. The maximum amount of coins will only ever be 1 Million coins. The minted coins are distributed through Proof of Stake.

Looks simple if all 100,000 are participating in staking
but if only half is staking how much will rate be? 20% from total current supply or 20% from current staking amount?Whatever balance you reserve for staking is where the 20% is calculated off.If you hold 100 for staking over the course of 1 year then that should work out at 20 coins staked on that balance once it has been permanently in staking.
