The 19 millionth Bitcoin was mined on Friday—a significant milestone considering there will never be more than 21 million.
And it means that 13 years into its existence, over 90% of all Bitcoin is now in circulation.
But if you’re looking forward to the historic moment when the last Bitcoin is mined, hoping it’s just around the corner, we hate to break it to you: Neither you, nor the current Decrypt team will see it, because in all probability miners won’t accomplish that until 2140.
This is because of a process called halving. To understand halving, you need to understand the Bitcoin mining process.
