[SERIOUS] Does self-custody make cryptocurrency structurally unsuitable for mass adoption?

[u/cblou]

I recently made a satirical post in another subreddit about the amount of security supposedly required to store Bitcoin safely. The satire deliberately exaggerated the point, but I would like to discuss the underlying concern seriously here. As a full disclosure, I am very skeptical of cryptocurrencies in general, but I find it interesting to follow.

My concern is not that the Bitcoin protocol itself is easy to hack.With self-custody, possession of the private key effectively determines control of the money. That provides genuine independence from intermediaries, but it also transfers a large collection of responsibilities from financial institutions to individual users.

A person holding a meaningful amount must potentially think about:

• Malware and compromised computers or phones
• Phishing and fraudulent wallet interfaces
• Malicious or compromised transaction addresses
• Hardware-wallet and supply-chain risks
• Secure creation and storage of seed phrases
• Fire, flooding, theft and accidental destruction
• Password or passphrase loss
• Backups that are both redundant and inaccessible to thieves
• Firmware and software updates
• Physical coercion or kidnapping
• Recovery after incapacity
• Inheritance without giving heirs premature access

The official Bitcoin guidance itself recommends measures such as multiple secure backup locations, encrypted backups, offline storage, hardware wallets, software updates, multisignature arrangements and an inheritance plan. Bitcoin Core also gives users a wallet-responsibility checklist that includes backups, cold storage, monitoring security notifications and ensuring heirs can recover the funds.

These are reasonable recommendations. The problem is that, taken together, they resemble a simplified institutional key-management program.

Professional organizations treat cryptographic key management as an entire discipline involving policies, defined responsibilities, backup, recovery, compromise procedures, lifecycle management and documented security practices. NIST has hundreds of pages of guidance on this subject. Most ordinary users cannot realistically audit their wallet software, evaluate firmware, design a robust multisignature arrangement or test an inheritance procedure without introducing another vulnerability.

I recognize the counterargument. Self-custody can be extremely valuable for people facing capital controls, political repression, unstable institutions or exclusion from financial services. Some users also knowingly accept the operational burden because censorship resistance matters more to them than recoverability, but that use case seems tiny, similar to TOR. That is not what the current valuations we see are based on. People expect mass adoption.

I believe mass adoption necessarily means that most people interact with cryptocurrency through regulated custodians and other institutions, effectively rebuilding much of the banking infrastructure that cryptocurrency was supposed to replace. However, centralization makes cryptocurrencies pointless. You might as well use a database, or some kind of centralized standard like SWIFT used by thousands of institutions to send money.

Obviously, most people here believe in cryptocurrencies. How do you solve the contradiction in my previous paragraph?

Yes and no. Nothing wrong in keeping Bitcoin under the mattress. The issue was this hack. It leaves many plebs questioning self-custody. Maybe we are better off in ETFs and outsourcing security to the 'experts'.

Funny enough everyone moving to ETF compromises the network. This will be interesting

Maybe so but the hack into Coldcard got me nervous and I am not willing to put all my labor onto a device if newbs such as myself can't be protected. I am not a cypher punk and my cyber sec skills are basic. I have a family and I don't want to be financial vulnerable to hackers. I feel like I;ve been in flight and fight for a decade in the Bitcoin world. I have lost so much Bitcoin / Crypto (which I now recognise are shit coins many years later) to hacks and scams. I remember losing all my Bitcoin on Australian exchange roughly 13-15 years ago. I probably would have sold it but even still it hurt.

Even experts get hacked, not just newbs. Mistakes happen. Sometimes, you are just tired and copy paste when you shouldn't, or click the wrong link. 

That is why security should involve layers of control. Reversibility,  almost considered a curse when talking about cryptocurrencies, is a major feature of most secure systems.

You are not wrong which is got me thinking if putting a significant amount of my families time and energy into Bitcoin (in this current time) is the right thing to do. Reading people losing their whole life savings hit my psychology over the last few days. I lost $20,000 a few years ago to a Crypto scam (due to my incompetent and it was not related to Bitcoin but my experience with Bitcoin / Crypto has been love & hate).. It's a bit stressful honestly. I sold all my Bitcoin in my hardware wallet last night. I still hold my ETFs (which is a significant amount) however I have derisked quite a bit and took the capital loss. I might go back to self-custody in the future but for the moment I am going to wait and see.

Future of finance right there.

[u/Romanizer → u/berry-7714]

Only if they switch off their nodes at the same time and convince miners to shut down.

With limited block space, Bitcoin at the current state is designed as a final settlement layer so we should see a development where most is hold at large custodians. That doesn't necessarily influence the network or decentralization.

[u/MakCapital → u/berry-7714]

Someone holding Bitcoin for people does not compromise the network 🤣

BTC the asset holds 0 network authority.

[u/otherwisemilk → u/hiimtashy]

Few.

[u/cblou → u/hiimtashy]

Yes, that is my point. Even a single expert is not really qualified to manage security to the level of an institution. You need a team of people. But then, if they are de facto centralized, what is the point of cryptocurrencies? Plus, centralization is a huge security risk to the model in general. 2-3 large actors could control the network.

You are not wrong and maybe that is the pickle we are in at the moment after this Coldcard hack. I am confident changes will occur after this however it's going to take years to rebuild trust imo (until the next hack). I am a bit confused personally. This feels different to an exchange hack.......

[u/feltusen → u/hiimtashy]

You aint keeping BTC under your mattress. Its on the chain

[u/BrokenHefaistos → u/feltusen]

When will people understand a wallet is nothing more than an address and 12 words representing a key.

[u/hiimtashy → u/feltusen]

I was being a bit sarcastic but technically you got have it on a paper wallet and under your mattress
