Bitcoins being digital-assets exist virtually on a public ledger, better known as the blockchain. And, every blockchain thrives on rules or protocols which all users follow whenever they update any records. 

Every blockchain has several metrics, and the protocols guide those agreed unanimously by the developers. Other metrics are relative and keep fluctuating concerning market variables. 

This post will be constructive towards helping you refresh your knowledge regarding the critical questions with how many bitcoins there are. 

As of now, the figures keep changing every other minute. So, how many bitcoins are there in circulation? Looks like a ridiculous question, but surely you asked yourself this before. Read on to grasp the critical notes around the entire scenario. 

How many Bitcoins are there in circulation as of 2020?

According to, records closing in quarter 2 of the year 2020 show a total of 18.52 Million in circulation.  Therefore, with mining capping at 21 million, how many bitcoins are left? Only 2.48 million to mine. 

Bitcoins in circulation is a relative figure. Why? 

Of the entire total of Bitcoins in circulation, part of it is lost, since owners have lost its public keys. A portion of it goes away through theft. 

Why do These Limits Exist?

Blockchains have upper limits beyond which mining halts.  For Bitcoin, the limit is 21 Million coins. Those limits exist to give legitimacy to a digital asset. And the legitimacy arises by creating scarcity- where ordinary money is ever scarce in supply. 

The opposite scenario would create oversupply situations, meaning Bitcoin would practically be worthless since everybody can mine it. 

Where do we currently stand with Bitcoin mining?

The total Bitcoin mined as of Month 3 of Quarter 3 of 2020  stands at 88.1%. Inference from data collection and analysis by the University of Cambridge credits 65% of bitcoin hashing or mining power to China.  Therefore, China alone contributes to 585 Bitcoins mining out of a total of 900 bitcoins daily. 

How many Bitcoin blocks are there today?

Data from indicates the total tally of blocks of the Bitcoin blockchain standing at 649,955. The figure increases on a day to day basis as more Bitcoin mining completes.  The site captures other details like the hash codes,  miner names, and the block’s size in bytes. 

How many Bitcoin users are there?

According to claims by Bitcoinmarketjournal, there are an estimated 7.2 Million Bitcoin users. And closing December 2019, the total number of wallets estimated was 42 Million.  

There are multiple occurrences that any single user can hold several wallets at a go. While it’s also hard to estimate the average amount each may have/own. 

How many Bitcoins have been lost?

Loss of Bitcoin arises for many reasons, like the fact that public keys are non-transferable.

How Many Bitcoins Have Been Stolen?

Parting Notes

Bitcoin metrics conform to those of other financial assets. They keep fluctuating with time alongside significant variables like supply and demand. With bitcoin, it is the whole equation of mining difficulty as the percentages inch towards 100%. 

As much as clarity exists regarding how many bitcoins are left for coins miners to work on, other relative metrics keep emerging: 

  • Can bitcoins blockchain allow miners to alter protocols to increase the number of bitcoin mining above 21 Million? 
  • What would happen in case a successful hard-fork takes effect to increase the mining cap? 
  • Quite a significant portion of Bitcoins is lost or stolen. Can it ever be recovered? 

The reality is bitcoins will keep increasing and so will the total mining capability. Ideally, the metrics keep changing day by day and you should maintain yourself updated to know about the flutuation of the currency. 

Most metrics come up from studies based on estimations without any party holding primary and credible details. Remember, there’s no holder of single-source data regarding bitcoin.
