> "Crypto" is useless. Bitcoin isn't. What unique properties does Bitcoin have that makes it useful that other cryptocurrencies don't, beside first mover advantage?
Bitcoin is provably the only decentralized system that has permissionless, borderless, digital scarcity. Other cryptocurrencies are less secure (the many direct forks, such as Bitcoin Cash and the like), less decentralized (Solana, BNB), less permissionless (any system that can be halted by its operators) or less scarce (Ethereum's emission schedule can be changed by a single organisation). Bitcoin's value (not in te…
Why do we need digital scarcity, exactly?

Ok, we agree that other cryptos are bad too.
>Bitcoin's value (not in terms of money, but in terms of usefulness) is an emergent property of the combination of proof of work, the difficulty adjustment, and its peer-to-peer nature.
But what is that useful to do? I agree cryptography and blockchains are nifty, but why do 1000's of decentralized computers need to do the work (and therefore duplicate/waste resources)? Couldn't one computer do it and make their work public so anyone/everyone could check their work?
You'll say something ambiguous thing about trust, but please give a concrete example when the above wouldn't work. Visa (and it's shareholders) have hundreds of billions of USD worth of incentive not to fuck up transactions (enough to buy enough electricity and ASICs to become 51% of miners), so why don't we let them do the work and then we check their work?
Is that bad because it's what we do now and it works?
