Entering the Fourth Epoch, 19,687,500 BTC has been mined and issued, equivalent to 93.75% of the terminal supply of 21M BTC. Thus there remains only 1,312,500 BTC to issued over the next 126 years, with 656,600 (3.125%) being issued across our current Epoch. Interestingly, each halving represents a point where:

The percent of supply remaining equals the new block subsidy (3.125 BTC/block vs 3.125% remaining).

50% of the remaining supply (1.3125M BTC) will be mined between the fourth and fifth halving.

Scarcity will Come slowly but surely
