<a href="https://thbusd.com/btc-usd/">Bitcoin</a>’s 20 Millionth Coin Set to Be Mined This Month

Key Highlights

  • Bitcoin’s 20 millionth coin is projected to be mined around March 11–15, 2026, according to blockchain data and current block production rates. This means 95.24% of all Bitcoin that will ever exist is already in circulation.
  • The remaining 1 million BTC will take approximately 114 years to mine due to the halving mechanism, with the final satoshi expected around the year 2140.
  • An estimated 2.3 to 3.7 million BTC are considered permanently lost, according to Chainalysis and River Financial research. This reduces the effective circulating supply to roughly 16–17.7 million coins.
  • The milestone coincides with Bitcoin trading at $68,000 after a volatile week, while spot ETFs absorbed $1.45 billion in net inflows over five days and Grayscale flagged the event in its 2026 institutional outlook.

Within the next few days, a Bitcoin miner will add a new block to the blockchain, marking a major milestone: the creation of the 20 millionth Bitcoin. This is a significant moment in the 17-year history of the network.

There won’t be any official statements, press events, or policy changes. It’s simply a continuous process – a digital record updating on a system that’s been running smoothly since January 3, 2009. However, this ongoing count represents something much more significant than just a number.

As of early March, about 19.997 million Bitcoin had been mined, according to the Clark Moody Dashboard. With roughly 450 new Bitcoin being created each day – a result of the 3.125 BTC reward given for each block – the total supply is expected to reach 20 million sometime between March 11th and 15th. This timeframe may vary slightly depending on how quickly blocks are added to the blockchain.

After that final stage, only one million Bitcoins will ever be available, and it will take over a hundred years to mine them all.

The Math Behind the Scarcity

Bitcoin has a built-in, unchangeable rule about how many coins can ever be created. The limit is around 21 million, though it’s technically a bit less (about 20,999,999.9769 BTC) because of how the code handles decimals. New bitcoins are produced through a process called mining, and the amount created is reduced by half roughly every four years – this is known as the halving.

As a researcher tracking Bitcoin’s development, I’ve observed a fascinating pattern in its mining process. The initial half of all Bitcoins were actually mined within the first three and a half years after the network went live, back in November 2012. However, it then took another four years to mine the next quarter. What’s really interesting is that with each new batch of coins mined, the process takes longer and yields fewer Bitcoins. It’s a slowing rate of production with each cycle.

Once Bitcoin reaches 20 million coins in circulation, new coins will be created much more slowly. By the 2040s, less than 30 Bitcoin will be mined each day. This rate will continue to decrease, falling below 2 Bitcoin per day by the 2060s. Experts estimate the last complete Bitcoin will be mined in the 2090s, with the very last fraction of a Bitcoin, called a satoshi, appearing around the year 2140.

As an analyst, I see that eventually, all 21 million Bitcoins will be mined. After that happens, no new coins will be created. The people who maintain the network – miners – will then depend solely on the fees paid for transactions to keep things secure and running.

Bitcoin’s annual inflation rate is currently less than 1%, which is lower than the estimated 1.5–2% annual increase in the gold supply. This rate will decrease even further after the next halving event, predicted for 2028. By the 2030s, Bitcoin’s inflation will be so low it won’t be a significant factor.

The Lost Coin Problem

The reported total supply of 20 million coins is misleading because not all of them are available for trading. A significant amount of these coins are lost or otherwise permanently unavailable.

Estimates from Chainalysis and River Financial suggest that between 2.3 and 3.7 million Bitcoin are permanently inaccessible. This happens when people forget the passwords to their digital wallets, lose or break the devices storing the Bitcoin, or pass away without sharing access information. A significant portion of this lost Bitcoin – around 1.1 million – is believed to be held by Bitcoin’s creator, Satoshi Nakamoto, and hasn’t been moved since the early days of the cryptocurrency in 2009-2010.

Currently, only around 16 to 17.7 million Bitcoin are actively being used for transactions. Even after the remaining 1 million Bitcoin are released over the next hundred years, the total amount of Bitcoin practically available for use might not exceed 18 million.

As of 2024, UBS estimates there are around 59 million millionaires globally. If every Bitcoin ever lost were found, there still wouldn’t be enough to give each of them even half a Bitcoin.

Why This Matters at $68,000

As an analyst, I’m watching Bitcoin navigate a volatile period. We saw a price dip to $68,000 on March 6th after a quick rise to around $74,000 earlier in the week. This pullback seems to be due to some short-term investors taking profits, combined with ongoing concerns about the geopolitical situation, particularly regarding the U.S. and Iran.

Despite recent price fluctuations, institutional investment in Bitcoin appears strong. U.S. spot Bitcoin ETFs saw about $1.45 billion in new investments over five trading days in early March, and no ETFs experienced any outflows on March 2nd, breaking a previous trend of Monday outflows. Data also reveals that the number of Bitcoin wallets holding between 100 and 1,000 BTC – often referred to as ‘sharks’ – has increased to almost 17,970 as of early March 2026. Additionally, a metric called the Exchange Whale Ratio reached 0.85 in late February – a level not seen since October 2015 – before decreasing, which analysts often interpret as a sign that selling pressure is easing.

Grayscale, a major player in digital asset management, predicts that 20 million people will be invested in crypto by 2026. They believe increasing concerns about traditional currencies are driving interest in digital money, which offers a clear, limited supply. Grayscale also anticipates that new laws supporting the crypto market will be passed in the U.S. by 2026, bringing Bitcoin more firmly into the mainstream financial system.

What It Means for Miners

Reaching 20 million coins highlights a long-standing issue: as the rewards for mining decrease, how will miners continue to operate profitably?

Right now, Bitcoin miners receive 3.125 BTC for each block they create, along with any transaction fees. In 2028, this reward will be cut in half to 1.5625 BTC. By 2032, it will shrink further to 0.78125 BTC. Based on today’s prices, these cuts mean miner revenue is roughly halved with each halving, unless the price of Bitcoin goes up or transaction fees increase to compensate.

Bitcoin mining is shifting from a system where miners primarily earn rewards to one where they earn through transaction fees. Currently, fees make up a small part of miners’ income. However, as the rewards miners receive for creating blocks decrease over time, the future security of the Bitcoin network will rely on users paying enough fees to keep miners operating.

We aren’t facing a crisis right now, as the current reward system will continue to generate significant income for at least the next few years. However, reaching 20 million users signals a change that’s already happening.

The Bigger Picture

Throughout history, no money system has ever been quite like Bitcoin. While gold has a limited amount, it’s hard to know exactly how much exists because new deposits can be found and mining technology improves. Traditional currencies have no limits at all. Bitcoin is unique because its creation is controlled by a fixed, public schedule, meaning everyone knows exactly how many coins will ever exist, and no single entity can change that.

Just because there’s a limited supply of Bitcoin doesn’t automatically mean its price will go up. Demand also plays a crucial role. However, reaching 20 million bitcoins in circulation strengthens the fundamental idea behind Bitcoin’s growing popularity – from early tech enthusiasts to large investment funds. This idea is that there will only ever be 21 million bitcoins, most are already in use, a good portion are lost forever, and the remaining bitcoins will be released slowly over a long period – longer than most organizations exist.

The program is currently executing, and the available resources are limited. This important step will happen regardless of whether people are noticing it.
