Chun Wang, co-founder of F2Pool and the first Bitcoiner to venture into space, says Bitcoin has little to fear from quantum computing. He argued that claims of its downfall are misguided. Furthermore, he added that Bitcoin’s cryptography remains strong despite new advances in computing.
Instead of worrying about speculative risks, Wang maintains that the crypto industry should start planning. He emphasises the need for Bitcoin’s role in a future where humanity expands beyond Earth.
Interplanetary vision for Bitcoin
Wang insists the conversation about Bitcoin’s future should shift from exaggerated threats to practical goals. In a post shared on X, he expressed that developers must focus on building systems. These systems need to make Bitcoin capable of functioning across planetary distances. Latency tolerance, in his view, will be critical for ensuring smooth transactions between Earth and potential colonies on Mars or further into space.
I’d bet that by the time humans settle on Mars and economic activity already begins there, quantum computers still won’t have cracked secp256k1. Instead of wasting time worrying about quantum computing, it makes far more sense to think about how to make Bitcoin latency-tolerant,… https://t.co/vycgtlWwKv

The entrepreneur has long envisioned Bitcoin as the universal settlement currency for humanity’s interplanetary expansion. According to him, Bitcoin’s structure and neutrality make it more suitable for this role than any alternative digital asset. He warned against relying on what he described as “fleeting altcoins” to handle the demands of an interplanetary economy.
Wang added that preparing Bitcoin for space colonization is not only practical but essential. This is because the timeline for such a milestone could arrive before quantum computing ever poses a real threat.
Quantum Fears Across Bitcoiners
Quantum computing has been advancing at leading technology firms. Projects like Google’s Willow, Microsoft’s Majorana 1, and IBM’s Blue Jay show incremental progress. Despite this, most applications remain confined to labs. Moreover, the technology still lacks any clear use case demonstrating its ability to disrupt established cryptographic systems.
This has not stopped speculation in the crypto community. Tesla and SpaceX chief Elon Musk even fueled the debate recently. He asked Grok, xAI’s chatbot, to estimate the probability of SHA-256 — Bitcoin’s core hashing algorithm — being cracked by a quantum computer. The question reignited online debates over Bitcoin’s resilience in the face of emerging technologies.
Based on 2025 assessments from NIST, IBM, and expert surveys, the probability of quantum computing cracking SHA-256 (via Grover's algorithm, reducing preimage search to ~2^128 operations) is near 0% in the next 5 years and <10% by 2035. It requires millions of error-corrected…

However, Wang rejected these fears, emphasizing that Bitcoin will still be intact when quantum computers come around. He argued that, by the time the SHA-256 is broken, humanity will have established itself in Mars and that the present discussions are just baseless anxiety.
Wang’s Space Legacy
Beyond his views on Bitcoin’s future, Wang’s legacy is tied to a milestone space mission. He travelled aboard the Fram2 mission. This mission flew over Earth’s pole with three other crew members.
During the mission, the team carried out 22 scientific experiments, including the first X-rays ever performed in space. The trip solidified Wang’s position not only as a crypto enthusiast but also as a figure determined to link BTC with space exploration by humans.
