85% of the 21 million Bitcoin supply cap has now been mined. The current issued supply since the genesis of the network has now moved over the 17.85 million mark. While the network currently issues approximately 1,800 bitcoin per day, this issuance will halve to 900 bitcoin per day around May 2020. It is estimated that the total supply of 21 million will be issued around 2140. There have been positive signs that fees will rise to compensate miners as the block subsidy halves every four years.
