| Do you extend the same reasoning to fiat? There are many centralized services that do dispute arbitration on top of USD. Those systems are built entirely outside of USD. PayPal for example doesn't have an account at the Federal reserve nor does it handle physical cash. They are effectively "off-chain" payment systems for USD. So I guess your question is, what are the advantages of BTC over a fiat currency like USD. The answer is two folds: 1) BTC has an open network (the Bitcoin blockchain) allowing users to exit payment systems for the purpose of self-custody or for interconnecting with other payment systems. There's no equivalent system with fiat. Self-custody of USD literally requires transporting and storing pieces of paper. You also can't directly transfer USD from PayPal to say, CashApp. 2) BTC has a predictable money supply. Fiat currency doesn't: money supply can be arbitrarily inflated. In addition to the above, Bitcoin enables the creation of payment systems that are more tightly built on top of it, like the Lightning network, which preserves many of the properties of Bitcoin (e.g. trustless). You could also build a dispute arbitration system where the arbiter just needs to be semi-trusted (e.g. there are schemes that can cryptographically prevent the arbiter from stealing escrowed funds, etc.). |
We are talking bout fiat? No.

No. The question is: what does the trustless blockchain offer when you still have to rely on a centralised trusted entity.

Which immediately means that whoever got in early and got the first initial supply is at great advantage compared to anyone who got in later. For example compared to any people born 20 years from now.

Could. Maybe. Should. Perhaps. That's all you can ever hear from crypto proponents.
