Former PayPal President Confirms Bitcoin Could Process Trillions Daily

Former PayPal president and Lightspark CEO David Marcus stated that eventually Bitcoin has a potential to handle trillions of dollars a day. This was in a recent interview where he emphasized the use of Bitcoin as open money network on the internet. Marcus is of the opinion that BTC will become a global settlement layer with real-time transactions of low cost.

Bitcoin to Dominate the World’s Finance

According to Marcus, the infrastructure of Bitcoin is prepared to scale with the help of the Lightning Network. He said that Lightning will allow near-free and instant transfers, whereas previous systems (SWIFT or Visa) are not instant. These networks handle about 5 trillion and 33 billion dollars every day respectively. Marcus believes that with increased adoption, Bitcoin will outdo them. He stressed that the shift will be gradual and gradual due to the increased popularity of wallets and embedded payment systems across the globe.

Lightspark, the company of Marcus, constructs Lighting Network infrastructure to facilitate the scaling of Bitcoin. By 2023 it has more than 20,000 active nodes and a 3,000% increase in capacity and this is still 20,000 times more than in 2023. It can carry out millions of transactions every second which makes the prediction made by Marcus technically possible. The company offers APIs and SDKs to developers, which enable companies to integrate Lightning payments.

Bitcoin Institutional Adoption

Bitcoin is still growing by institutional investment. This is after an inflows record and regulatory transparency in the key markets last year. The market capitalisation of BTC is almost 1.3 trillion, and the on-chain transactions are approximately 15 to 20 billion a day. Marcus claimed that the increasing confidence in institutions would act in favor of Bitcoin as a transition to financial infrastructure as opposed to a speculative asset.

Marcus said stablecoins on Bitcoin were one of the main factors of mass adoption. Stacks and RGB have become projects that enable the issuance of stablecoins over the Bitcoin network. The combination of assets that are stable and Lightning has the potential to drive day-to-day business and international payments. It can theoretically support millions in a second with Lightning. The hash rate of Bitcoin is at all-time peaks in 2025, which adds to its security and reliability. Marcus had anticipated that after infrastructure maturity, BTC can compete with the global payment networks in terms of size and performance.
