How Many Bitcoins Are There? The Difference Between Real and Capped Supply

THELOGICALINDIAN - Despite the 21 actor cap placed on Bitcoin absent bill hacks and user absurdity accept ensured that a ample allocation of this capped accumulation will never reenter circulation

Bitcoin’s absence is a basic aspect of its value proposition. The project’s bearding creator, Satoshi Nakamoto, advised the arrangement with a capped accumulation aloof shy of 21 actor BTC. But afterwards accounting for bill that are absent forever, how abounding Bitcoins are absolutely accessible?

How to Lose Bitcoin

The abstract absolute on Bitcoin’s accumulation is 21 actor coins. But the absolute accumulation of Bitcoin is abundant lower than this limit.

Unlike banknote in a coffer account, back the clandestine key or berry byword for a Bitcoin wallet is lost, those bill are gone forever. An online cyberbanking or ATM pin can be displace because the coffer has ultimate ascendancy of all accounts.

Bitcoin is self-custodial. This agency that if a user loses their coins, it is absurd to retrieve them. This is not the case if the bill are stored application a third-party custodian, like an barter or added value-add service.  

Satoshi Nakamoto, the architect of Bitcoin, meant for it to be advised this way. They are believed to be the ancient BTC miner, accidental massively to the absolute bulk of absent Bitcoins.

Back in the aboriginal canicule of Bitcoin, afore it had a amount or aqueous exchanges, it was an action for hobbyists. People mined BTC on their claimed computers as the adversity was acutely low. The arrangement was infantile, and some may accept alike deleted their clandestine keys on purpose, cerebration this “magic internet money” would never accretion value. 

Tracking Real Supply

CoinMetrics, a abstracts close accoutrement the crypto space, ran the numbers to appraisal the absolute bulk of Bitcoin that has been bound abroad forever. To do this, the close undertook a accurate UTXO, or Unspent Transaction Outputs, assay and looked at bill that accept been abeyant back July 2010.

Their analysis assured that as of November 2024, over 1.5 actor Bitcoins accept been finer burnt. In the apple of crypto, the appellation “burnt” is addition of adage that tokens are absent always and no best accord to a network’s accidental supply. 

Surprisingly, there were bristles factors that contributed to this number.

Firstly, back Satoshi mined the aboriginal Bitcoin block, the aboriginal 50 BTC mined were never included in a UTXO set. That agency these bill never existed, admitting the transaction for mining them was real. 

Second, there are two sets of identical agenda signatures for four altered affairs area a miner receives their block reward. 

At blocks 91,722 and 91,880 the signature was the same, abatement the accolade accustomed at block 91,772 as it came first. The aforementioned adventure was replicated at blocks 91,812 and 91,842. One hundred Bitcoins were asleep as a aftereffect of this bug.

Third, there were two blocks at which miners didn’t affirmation their block accolade and addition area the miner didn’t affirmation their transaction fee reward. A absolute of 20.5 BTC was absent this way.

Fourth, some bulk of BTC was beatific to burner addresses. All but one, which was for Counterparty, were artificial addresses, afire a absolute of 2,214 BTC.

The final acumen for absent Bitcoins is accompanying to “zombie coins.” These are bill that haven’t been confused in about 10 years; they annual for a majority of mined bill that are no best a allotment of circulating supply. The alone abstracts point actuality is 1.496 actor BTC that were mined by Satoshi and never touched. 

In fact, none of Satoshi’s addresses accept anytime apparent any transaction activity.

How Many Bitcoins Are There?

Since 1.5 actor Bitcoins are about affirmed to be lost, we can appraisal today’s absolute accumulation with some amount of accuracy. 

In total, a best of 19.5 actor Bitcoins can anytime exist, admitting claims of a absolute cap of 21 million.  

CoinGecko abstracts shows that 18.294 Bitcoins accept been mined so far. So the cardinal of Bitcoins that abide today is aloof shy of 16.8 million.

There are some added factors that appear into play. For starters, we cannot accurately adumbrate how abounding thousands, or millions, of Bitcoins accept been absent in the aftermost decade. 

Further, Bitcoins baseborn from exchanges like Mt. Gox and Bitfinex accept hardly been moved. The proprietors of the PlusToken Ponzi scheme are the exception, offloading chunks of their boodle on Huobi.

This admiration doesn’t action a absolute calculation for how abounding bill lost, but it helps authorize the lower absolute of absolute bill lost, as able-bodied as the high absolute for absolute supply.
