How Many Bitcoins Are There in Total?

bitcoin supply

Key Takeaways
  • How many Bitcoins are there? Simply put, Bitcoin has a fixed supply of 21 million coins. 
  • Approximately 19.73 million Bitcoins are already in circulation today, with roughly 1.5 million remaining for mining.
  • Halving events decrease the network’s mining rewards, and experts predict the final Bitcoin will emerge in 2140.
  • Lost private keys, hardware failures, and other errors permanently destroy BTC. Lost coins decrease its supply, making it scarcer and potentially increasing its price.

Many people view cryptocurrency as an investment opportunity or, at the very least, a hedge against inflation. Security’s 2024 cryptocurrency report reveals that about 40% of American adults are cryptocurrency owners, and 63% look forward to increasing their holdings in the upcoming year.

With profitable returns like those seen with Bitcoin, cryptocurrency becomes a lucrative investment option for many. Investing in crypto requires tact, patience, and resilience. You can make informed investment choices if you understand the fundamentals, such as supply. 

This article explores Bitcoin’s supply dynamics, highlighting its current circulation, supply limit, mining, and lost BTC.

How Many Bitcoins Are There?

There will only ever be 21 million BTC. Satoshi Nakamoto added this limit to the network’s source code, and network nodes enforce it. This fixed supply contrasts traditional fiat currencies, which central banks can print at will. The only way to add new BTC is through a specialized process called mining. More on it below.

To mimic the scarcity of precious metals like gold, the rate of new Bitcoin generation gradually decreases via the halving process. Occurring roughly every four years, the halving ensures a steady decline in the issuance of new coins. While the exact reasoning behind the 21 million cap remains a mystery, its impact is undeniable. By imposing a finite supply, Bitcoin introduces a unique economic dynamic that has captured the world’s attention.

How Many Bitcoins Are in Circulation?

At the time of writing, approximately 19.73 million BTC were in circulation. The Bitcoin halving occurs every four years, cutting the mining rewards in half. It controls how many new coins enter into circulation. The last halving took place in April 2024.

Bitcoin’s deflationary mechanism sets a clear timeline for its total supply, with miners expecting to produce the final Bitcoin around 2140.

How Are New Bitcoins Created?

Bitcoin’s creation is a decentralized process. Nodes across a peer-to-peer network generate new coins and any attempt to circumvent these rules results in worthless, rejected coins.

Bitcoin miners are users with specialized computers who race to solve complex mathematical puzzles, receiving block rewards for their efforts. The first to find the correct solution adds a new block to the Bitcoin blockchain and receives a predetermined amount of BTC, plus any transaction fees included in the block. These rewards incentivize miners to contribute their computing power to secure the network. 

How Many BTC Are Left To Be Mined?

Approximately 1.5 million BTC remain. While this might seem substantial, the rate of new coin creation is steadily decreasing due to the cyclic halving, so those remaining coins will take a significant time to mine. Every ten minutes, miners add a new block to the Bitcoin blockchain, releasing 3.125 coins into circulation with each. Mining is expected to conclude around 2140.

What Happens When All Bitcoin Has Been Mined?

The Bitcoin network will cease producing new coins. While the block subsidy vanishes, miners will continue collecting transaction fees. Miner income and Bitcoin security will depend solely on these fees.

Why Are There Only 21 Million Bitcoins?

When you discover the total supply of BTC will always be 21 million, you may question the rationale behind this specific number chosen by the creators. What’s the significance of this cap?

Think of it this way: if you knew that no more than a certain number of rare objects would ever exist, wouldn’t that object become more valuable over time? The same principle applies to Bitcoin. The 21 million limit creates an intentional scarcity to protect Bitcoin’s value as it becomes harder to obtain.

As the world increasingly turns to digital currencies, Bitcoin’s limited supply becomes a hedge against inflation. So, the next time you hear about Bitcoin’s 21 million cap, remember—it’s not just a random number. It’s a vital part of what makes the currency valuable.

How Many Bitcoins Have Been Lost?

Imagine having BTC worth thousands of dollars but realizing you can’t access it. Unfortunately, this is a reality for several unfortunate individuals. A significant portion of BTC is lost forever, contributing to its deflationary nature.

According to a Chainalysis report, approximately 20% of all Bitcoins have stayed in their current addresses for over five years, suggesting they’re lost. But what does “lost” mean?

  • Lost Private Keys: The most common way Bitcoin is losing access to the corresponding private keys. This can either be because your wallet software has stopped working, or else because you’re using a hardware wallet that has been lost, stolen or damaged, and you haven’t recorded the seed phrase. Remember, this mnemonic phrase is the back-up for all the private keys in your crypto wallet, so recording it and storing your seed phrase carefully can be the difference between securing your crypto and losing it for good.
  • Human Error: Sending Bitcoin to an inactive wallet address without a way to reverse the transaction is another commmon cause of lost crypto.
  • Deceased Owners: In select cases, individuals have passed away without sharing their private keys or wallet information, making their Bitcoin inaccessible.

These losses highlight Bitcoin’s deflationary status, as each lost coin reduces the total supply, potentially increasing the value of those that remain accessible.

How Many Bitcoins Are on Exchanges?

Crypto exchanges hold approximately 2.73 million Bitcoins. CryptoQuant offers a live balance view for those keen to stay updated, letting you track these reserves in real time.

But why does this number matter? The availability of Bitcoin on exchanges directly affects market liquidity. Generally speaking, high availability means lower prices, low availability means higher prices. The availability of BTC on exchanges can offer a glimpse into market sentiment, providing hints about where the market might be heading.

Closing Thoughts

As with all investments, you must understand the basics, like supply and demand. With Bitcoin, the limited supply ensures any increase in demand improves its value. Therefore, Bitcoin’s token dynamic lays a lucrative foundation for investing in cryptocurrency. However, always remember to do your own research before purchasing any cryptocurrency.

FAQs

How many Satoshis in a Bitcoin?

One bitcoin consists of 100 million satoshis (sats), with each satoshi representing 0.00000001 BTC. Satoshis are the smallest unit of bitcoin, making up the subunits that form a full bitcoin.

Why did Satoshi choose 21 million?

Satoshi’s decision was likely influenced by the desire to create a digital asset with a controlled scarcity, mimicking the limited supply of gold. Satoshi made Bitcoin deflationary by capping its supply, increasing its rarity and potential value. Bitcoin’s scarcity drives its demand and value in the market.

What is the Bitcoin halving?

The halving is a scheduled event in the protocol that reduces the mining reward by half every 210,000 blocks, happening every four years. The halving reduces the issuance rate for new Bitcoin and creates scarcity.

When will the last Bitcoin be mined?

Miners will extract the final Bitcoin around 2140. By then, repeated halvings will reduce block rewards closer to zero. After this, miners will sustain the network through transaction fees, transforming Bitcoin into a purely deflationary currency.
