Bitcoin Passes 20 Million Minted Coins, Signaling Long-Term Rarity

Bitcoin recently surpassed a significant milestone with over 20 million coins mined, representing more than 95% of the total 21 million that will ever exist. This event highlights the cryptocurrency’s fundamental characteristic of limited supply, differentiating it from traditional fiat currencies.

Understanding Bitcoin’s Limited Supply

Unlike currencies like the U.S. Dollar or the Euro, which can be printed or digitally created by central banks, Bitcoin has a pre-defined emission schedule encoded into its protocol. This hard cap of 21 million bitcoins was established in 2009 and requires broad network consensus to change.

The Mining Process and Halving

New bitcoins are introduced into circulation as a reward for “miners” – operators who use powerful computers to verify transactions on the network. Approximately every four years, the reward for mining is halved, a process known as “halving.” The most recent halving occurred in April 2024, reducing the reward to 3.125 bitcoins per block Parket Newsletter.

According to Simon Peters, a cryptocurrency analyst at eToro, “It took approximately 17 years to mine 20 million bitcoins. However, due to the halving mechanism, it will take approximately 114 more years to mine the remaining one million, so the last bitcoin should be mined around 2140.”

Implications of Scarcity

The milestone of 20 million mined bitcoins underscores the digital currency’s inherent scarcity. While 20 million bitcoins have been mined, the actual number available on the market may be lower due to lost coins – resulting from forgotten access data or lost digital wallets. Analysis from cryptocurrency exchange Kraken suggests the circulating supply is less than the total mined amount Parket Newsletter.

The Future of Bitcoin Mining

As the emission reward decreases, transaction fees will become increasingly important for miners. These fees are expected to become the primary incentive for maintaining the network’s security. The interplay between supply and demand will also significantly influence Bitcoin’s future price.

Peters notes, “If the demand for Bitcoin continues to exceed the amount of new Bitcoin coming to the market each day from miners and secondary sellers, and at the same time a large portion of holders are unwilling to sell at current prices, the market may be poised for a more significant upward movement in the coming months and years.”

Institutional Adoption and Market Impact

Bitcoin is attracting increasing attention from institutional investors following the approval of exchange-traded products (ETPs) in the U.S. Since their launch, tens of billions of dollars have flowed into U.S. Bitcoin ETFs, with BlackRock’s iShares Bitcoin Trust holding approximately $58.5 billion in assets as of mid-March Parket Newsletter.

This milestone is viewed by some as confirmation of the system’s functionality as designed over 15 years ago, while others question whether limited supply alone will be sufficient to sustain Bitcoin’s long-term value and relevance.
