Bitcoin bull and Strategy founder Michael Saylor has doubled down on the long-term value of BTC amid fast-changing geopolitical and cryptocurrency adoption trends.

Saylor took the stage with a keynote speech at the BTC Prague 2025 event on Saturday, predicting that the price of Bitcoin would hit $21 million in 21 years.

“I think we’re going to be $21 million in 21 years. It’s a very special time in the network. Maybe the one time in the history of the network where you look out 21 years and you see $21 million,” Saylor stated.

Saylor’s latest bullish Bitcoin prediction is a massive increase from his previous forecast made at the Bitcoin 2024 conference in Nashville last year, when he predicted that Bitcoin would hit $13 million by 2045.

Massive adoption that “nobody guessed”

In the keynote, Saylor reasoned his growing bullishness on the Bitcoin market with many geopolitical, regulatory and adoption developments, which he said nobody conceived last year.

“Stuff that’s happened in the past 11 months has been extraordinary. The White House has embraced Bitcoin. This is an extraordinary development. We didn’t anticipate this,” Saylor said.

Saylor emphasized that he has always been bullish on Bitcoin, even when it plummeted to $16,000 in the last crypto winter, but Donald Trump’s presidential victory last November “brought a sea change in politics,” he stated.

“Although we thought we might have a pro-Bitcoin president, we didn’t think we’d get a strategic Bitcoin reserve. We didn’t think that the president would say America would be the Bitcoin superpower of the world. This is an amazing development,” Saylor added.

The Strategy founder also mentioned growing regulatory and legislative developments around crypto, referring to three crypto-related bills progressing in the US, including the stablecoin-focused Genius Act, the Digital Asset Market Clarity Act and the Bitcoin Act.

“This is something nobody guessed, no one conceived of a year ago. States in the United States are embracing Bitcoin,” Saylor said.

Where does Saylor hold Strategy’s BTC?

Saylor’s new bullish forecast on Bitcoin comes amid Strategy (formerly MicroStrategy) continuing to aggressively accumulate more BTC, purchasing $1 billion worth of BTC last week.

Holding 592,100 BTC as of June 15, 2025, Strategy has not publicly disclosed where and how the company holds its BTC fortune, with Saylor rejecting the idea of publishing proof-of-reserves due to security concerns.

Saylor came under fire last year for also rejecting the concept of self-custody, or the way of holding BTC without relying on any third party, which remains one of the core Bitcoin ideas in the BTC community.

After facing community backlash for suggesting that Bitcoin holders should rather trust their assets to banks, Saylor reversed his stance on self-custody, stating that he supported it for “those willing and able” in October 2024.

In the meantime, the concept of self-custody continued to gain traction at the BTC Prague event, with attendees showing increased interest in “be your own bank” principles.

“BTC Prague continues to attract a strongly Bitcoin-focused crowd, most attendees were deeply engaged with the future of Bitcoin,” Danny Sanders, chief commercial officer at the hardware wallet company Trezor, told Godleak.

One of the main sponsors of BTC Prague, Trezor, welcomed more than 5,000 visitors at the conference, Sanders said. Those included a “vibrant mix of developers, Bitcoiners, and newcomers — all genuinely interested in open-source tools and the principles of self-custody,” he added.
