I just checked the Bitcoin numbers and it's interesting to see how it approaches that milestone of 20 million coins in circulation. Currently, we're around 20 million, so we're practically there.

But what really matters to observe is what comes next. Understanding what mining cryptocurrencies is essential to grasp why the end of Bitcoin's schedule is so different from the beginning. In the early years, miners could obtain thousands of bitcoins relatively quickly. Today? Well, things are completely different.

According to the network's calculations, the last million Bitcoin—those final bitcoins remaining to be mined until reaching the 21 million limit—could take approximately 114 years to complete. Yes, you read that right. 114 years.

This happens because the reward for mining cryptocurrencies like Bitcoin is halved approximately every four years in what is known as a halving. With each reduction, miners receive less BTC per validated block, meaning the issuance rate slows down significantly. It's a brilliant mechanism of programmed scarcity, but it also means that as we approach the 21 million maximum, issuance becomes practically negligible.

What's interesting is that this underscores one of Bitcoin's fundamental design principles: absolute scarcity. Unlike fiat currencies that can be printed indefinitely, Bitcoin has a hard and predictable cap.

For those tracking these numbers on Gate or another exchange, this is something worth keeping in mind. It's not just a fun fact; it's part of Bitcoin's value proposition as a long-term store of value.
