I want to know the total amount of coins, each block the number of coins? And every time is to reduce the coins?
In theory, the coin doesn't have a max limit. 40 billion coins will be distributed in approximately 12 months, with an additional billion being mined annually thereafter.
The current reward is 25k per block, at block 600k it will halve to 12.5k, at block 800k it will halve to 6.25k, at block 1MM it will halve to 3.125k, etc..., until it reaches a steady 1k reward to ensure network stability.
