Bitcoin has already grown into a massive system with users spreading worldwide. It was believed that as long as the Bitcoin market expanded, wealth could be increased. However, something unusual is happening now. After reaching a peak of over $126,000 in October 2025, the price of Bitcoin is currently trading at around half that value, at around $60,000-$70,000. The blockchain used by Bitcoin has a mysterious mechanism called mining. This cryptocurrency requires a massive amount of computational work using a large number of computers, known as mining. This mining process involves enormous calculations being performed all over the world. To keep these calculations running, a huge amount of electricity is consumed to power and cool the computers.
Even Bitcoin, which was said to increase in value, is now facing a dark shadow. One of these shadows is quantum computing. It is said that the threat of cryptography being deciphered by quantum computers is slowly creeping in. There are concerns that quantum computers could crack encryption, potentially undermining the reliability of blockchain-based decentralized systems. Bitcoin is under threat from quantum computers. If highly accurate quantum computers are developed, there is a risk that transaction encryption could be cracked, disrupting transactions. It has also been suggested that approximately 25% of Bitcoin could be stolen by hackers controlling quantum computers. Some experts say that blockchain companies will continue to be apprehensive about the evolution of high-performance quantum computers. This is reflected in the fluctuations in their stock prices whenever news of encryption cracking spreads.
Finally, I offer an idea that could boost Bitcoin’s momentum. As long as the trend towards environmental consciousness continues, tools that consume electricity lavishly will be phased out. A prescription for this is solar power generation in outer space, as advocated by Elon Musk and others. It is even said that the performance of mining and AI is proportional to the amount of electricity consumed. The idea is that this large amount of electricity could be generated in outer space where sunlight is uninterrupted. Inexpensive artificial satellites are already in practical use. The idea of generating solar power using satellites with giant panels is also becoming a reality. Another solution is to counter quantum computers. American startups are working on developing blockchain technology that is resistant to quantum computers. The technological improvements they are making may be able to compete with high-performance quantum computers. For improved quantum computer resistance, a blockchain method called a quantum-resistant ledger is being developed. Blockchain systems that protect information from quantum computers and ensure power consumption seem likely to survive in the world to come.
