In 1983, American cryptographer David Chaum conceived of a type of cryptographic electronic money called ecash. Later, in 1995, he implemented it through Digicash, an early form of cryptographic electronic payments. Digicash required user software in order to withdraw notes from a bank and designate specific encrypted keys before they could be sent to a recipient. This allowed the digital currency to be untraceable by a third party.
The first cryptocurrency was bitcoin, which was first released as open-source software in 2009. As of June 2023, there were more than 25,000 other cryptocurrencies in the marketplace, of which more than 40 had a market capitalization exceeding $1 billion. As of April 2025, the cryptocurrency market capitalization was already estimated at $2.76 trillion.
While both values have fluctuated wildly in the short term, investors who approached them as long-term investments reaped the rewards. Additionally, some experts expect emerging technologies, new regulations, and more widespread adoption to fuel the growth of the cryptocurrency industry.

MicroStrategy has by far the largest Bitcoin portfolio held by any publicly-traded company. The business analytics platform has adopted Bitcoin as its primary reserve asset, aggressively buying the cryptocurrency through 2021 and 2022. As of August 30, 2022, the company had 129,699 Bitcoin in its reserve, equivalent to just over $2.5 billion.
As compensation for spending their computational resources, the miners receive rewards for every block that they successfully add to the blockchain. At the moment of Bitcoin’s launch, the reward was 50 bitcoins per block: this number gets halved with every 210,000 new blocks mined — which takes the network roughly four years. As of 2020, the block reward has been halved three times and comprises 6.25 bitcoins.
The first chain to launch smart contracts was Ethereum. A smart contract enables multiple scripts to engage with each other using clearly defined rules, to execute on tasks which can become a coded form of a contract. They have revolutionized the digital asset space because they have enabled decentralized exchanges, decentralized finance, ICOs, IDOs and much more. A huge proportion of the value created and stored in cryptocurrency is enabled by smart contracts.
