Who is Jack Dorsey? The $4.3 billion bitcoin maximalists' encryption empire

Jack Dorsey, as the co-founder of Twitter and Block (formerly Square), has long been an important figure in the technology and finance sectors. As of 2025, his net worth reached $4.3 billion, a significant portion of which is closely tied to his encryption asset investments and Blockchain involvement.

Dorsey's firm support for Bitcoin and the concept of decentralization has profoundly shaped his financial empire. Despite his skepticism towards Web3, his strategic moves in the encryption space have solidified his position as a key player in the digital assets revolution.

##The Source of Wealth for Tech Giants

Dorsey's wealth primarily comes from his stake in Block and personal Bitcoin investments. He holds about 13% of the circulating shares in Block, which are worth approximately $3 billion as of 2025.

He was once an important shareholder of Twitter, but after Elon Musk's acquisition, his position in the company was valued at about $388 million. Dorsey's wealth has not been smooth sailing; in March 2023, when Hindenburg Research released a report shorting Block, his wealth shrank by $526 million in a single day.

##Bitcoin Minimalists

Dorsey is a famous "Bitcoin extremist," and his Crypto Assets investment strategy focuses almost entirely on Bitcoin, avoiding other Crypto Assets and Blockchain projects. This singular focus has set him apart in the crypto space, whereas diversification is often the norm.

It is estimated that Dorsey personally holds about 4,709 coins of Bitcoin, with a purchase cost of 50 million dollars. With the volatility of Bitcoin prices, these holdings may significantly increase in value by 2025.

Since 2019, Dorsey has publicly stated his strategy of regularly purchasing $10,000 worth of Bitcoin each week. At the price at that time, this amounted to buying about 2.7 BTC weekly.

##Block: Building the Bitcoin Financial Ecosystem

Under Dorsey's leadership, Block has transformed from a payment processing company into a diversified fintech company focused on Blockchain technology. The company's Cash App is a peer-to-peer payment service with integrated Bitcoin buying and selling features, which has become a significant driver of Bitcoin growth.

In 2024, Block's Bitcoin revenue reached $5.8 billion, a 35% increase from the previous year. Cash App alone facilitated over $10 billion in Bitcoin transactions in 2024.

As of June 30, 2025, Block Company owns 8,692 Bitcoins, with a cost of $272 million and a fair value of $932 million. The company increased its holdings by 108 Bitcoins in the second quarter of 2025.

Block will revalue its Bitcoin holdings at the end of each quarter based on market prices, and will include the gains and losses in the "Bitcoin Investment Revaluation Gains and Losses". In the second quarter of 2025, Block recognized a Bitcoin revaluation benefit of 212 million dollars.

##Promoting Bitcoin as a Daily Currency

Dorsey's vision for Bitcoin goes far beyond its investment value. He has repeatedly emphasized that he believes Bitcoin will become the "native currency of the Internet."

In 2018, he stated at the Consensus Conference: "The internet needs a 'native currency', and a native currency will also emerge. Although I don't know who will ultimately win, I hope it's Bitcoin."

Under his leadership, Block has been promoting the daily use of Bitcoin. In May 2025, Block enabled Square merchants to start accepting Bitcoin payments, allowing merchants to settle in Bitcoin or local currency after consumers pay using Cash App.

Block plans to promote Bitcoin payment functionality to millions of merchants (excluding New York and some international markets) in the second half of 2025.

##Critical Engagement with Web3

Although Dorsey is a staunch supporter of Bitcoin, he is skeptical about Web3. His skepticism mainly stems from concerns about centralization and the influence of venture capital.

However, this did not stop him from exploring decentralized technologies beyond Bitcoin. Dorsey demonstrated a strategic interaction with Blockchain technology through Block and his personal investments, which aligns with his vision for decentralization.

For example, the TBD project of Block aims to create decentralized financial services, demonstrating Dorsey's interest in blockchain applications beyond Crypto Assets.

In November 2023, Dorsey led an investment of $6.2 million into the revolutionary Bitcoin mining pool OCEAN. This decentralized mining pool aims to enhance the decentralization of Bitcoin through a non-custodial payment system that directly pays miners their earnings.

##Long-term Commitment to Bitcoin Development

Dorsey, through the so-called "Jack Dorsey Commitment," promised to provide a total of 5 million dollars to support the advancement of the Bitcoin protocol. This funding will be disbursed over five years, with 1 million dollars allocated each year.

He also supports the Bitcoin Lightning Network, which is a second-layer protocol designed to improve the scalability and transaction speed of Bitcoin. Dorsey appeared on Stephen Livera's podcast and stated that Square will integrate the Lightning Network in the near future.

##Dorsey's Wealth Philosophy and Personal Habits

Despite having billions of wealth, Dorsey maintains a relatively simple lifestyle. He reportedly gets nine hours of sleep every night as part of his daily routine.

Dorsey does not have a university degree; he dropped out before completing his studies and followed a path similar to other tech entrepreneurs.

##Future Outlook

As the Blockchain field continues to develop, Dorsey's influence and wealth may be closely tied to the success of Bitcoin and decentralized technology.

His unique approach combines Bitcoin minimalism with selective Blockchain participation, making him an influential figure in the ever-evolving Crypto Assets space.
