The key problem for Bitcoin owners is not volatility or regulators' actions at all, but excessive self-confidence in their own security. Most investors keep funds in a wallet with a single key and sincerely believe they fully control their protection. In reality, such a wallet depends on dozens of programs and devices that an ordinary person is unable to verify.
How the dispute began
A discussion on X about who should even self-custody Bitcoin revealed a fundamental disagreement. One user stated that self-custody is far from suitable for everyone: if a person cannot safely handle even the simplest single-key wallet, they are better off not holding coins at all. Everyone has made mistakes and lost Bitcoin at some point, and learning to "never make mistakes" is impossible. Moving to a multi-key wallet before mastering a simple one only complicates life without adding protection. The post garnered over 24,000 views.
Hugo, founder of the Bitcoin storage service Nunchuk, called this position arrogant. People capable of personally verifying every detail of their wallet are, by his estimate, few and far between. A wallet runs on a device that has a processor, firmware, an operating system, and numerous software components. Each of them must be trusted, even if the owner doesn't realize it. Security specialists know this from experience.
If a person understands these risks and still chooses a single key, that is their right. But feeling smarter than everyone else on that basis is not warranted.
Why multisig is more reliable
Multisig is a wallet where transferring coins requires signatures from several keys at once. They can be stored on different devices and in different programs. If one device is compromised, the money won't be lost.
Bitcoin is valued for requiring minimal trust. But trust cannot be eliminated entirely: one has to trust that the downloaded program isn't counterfeit, that the network operates honestly, that developers haven't introduced malicious code. No one disputes this. Yet people treat their own wallet differently — they are certain they have personally verified all the devices and programs through which their coins pass. Though in reality this is just as impossible as verifying all of Bitcoin single-handedly.
Hugo called this a contradiction: a person acknowledges that Bitcoin requires some trust but refuses to acknowledge the same about their own wallet. Someone who honestly sees Bitcoin's weaknesses is more likely to choose multisig. Only a presumptuous person can believe they definitely won't be hacked.
He also disagreed that people lose money more often with multisig. According to him, he has hardly ever heard of Sparrow, Blue, or Nunchuk users who lost Bitcoin from such a wallet. Meanwhile, single-key wallet owners lose coins or access to them almost daily. Most often — due to mistakes with the additional passphrase to the seed phrase. Such support requests come in constantly.
Storing a large sum on a single key is risky, even if the device seems reliable. As AI-powered attacks grow, there will be more victims among such wallet owners. Strengthening protection and moving to multiple keys is worth doing before that happens.
Cryptalist analysis: The discussion reflects market maturity: as Bitcoin's capitalization grows, the cost of an operational error grows exponentially, and institutional holders are already mass-migrating to multisig schemes. For retail investors, the key factor remains not the complexity of the tool but discipline and understanding of the threat model. The industry is expected to shift further toward standardization of multisig practices and educational solutions.
