"It's very hard for me sitting here to give you a [bitcoin] price prediction," Palihapitiya, who founded venture capital company Social Capital in 2011 and has recently become known as the SPAC king for his support of the alternative investment vehicles, told CNBC this week. "But I can pretty confidently say that bitcoin, I think, has effectively replaced gold. And it will continue to do so. And so that market cap is just going to grow."

While Palihapitiya likes other cryptocurrencies—including the buzzy, upstart solana—he said his crypto holdings are mostly limited to bitcoin.

"I haven't put a lot of money outside of bitcoin obviously," he said. "You know, tens of millions, hundreds of millions, like small capital right now. It could get very big. But irrespective of what I do, I will say is we all need to pay attention to it because I think the implications are enormous."

Palihapitiya has previously predicted bitcoin could climb as high as $200,000 per bitcoin one day—a price that would give bitcoin a market capitalization of around $4 trillion.

Bitcoin, which this time last year was trading at just $10,000, has soared over the last year, adding over 300% and causing the wider crypto market to explode in value. The bitcoin price has risen as investors increasingly name bitcoin as a hedge against inflation and predict it will serve as a digital alternative to gold.

Meanwhile, bitcoin and cryptocurrencies are facing a regulatory backlash with China cracking down heavily on crypto trading and the U.S. Securities and Exchange Commission (SEC) chair Gary Gensler promising to ramp up scrutiny of the crypto market. Wall Street legend Ray Dalio has warned governments and regulators will eventually try to "kill" bitcoin if it continues to grow.

"I think [bitcoin is] very hard to kill," added Palihapitiya. "So technically, it's very difficult. Just the way that it's architected, it is the most profound iteration of the internet that we've seen."
