1. Please don’t repeat the No True Scotsman train of argument again and hand wave away the problem by blaming it on “incompetence” - it removes the explicit malice those contracts were coded with. 2. I am struggling to see how this is/would/could ever be solved by crypto.

2. It's not solved by crypto, but then crypto doesn't charge a 3% commission for money transfer. The cost of a stablecoin transfer is a couple of pennies.

> The cost of a stablecoin transfer is a couple of pennies.

The cost of an authorized stablecoin transfer is.

The cost of an unauthorized stablecoin transfer is infinite. The cost of an unauthorized credit card transaction is $0.

The credit card is associated with a checking account. Fraudulent transactions on checking accounts and debit cards do happen, with or without an ATM. They do occasionally get reported in the news, and the bank will not protect or refund you for them, especially if it's large.

Even if we ignore the fact that I said "an unauthorized credit card transaction", that's all still incorrect.

No, not necessarily. Several of mine are not. For example, Chase will happily accept payments in cash via their branches. https://www.chase.com/personal/credit-cards/education/basics...

Deeply wrong. They are, in most cases, required to do so by federal law.

"The Electronic Fund Transfer Act (EFTA) and Regulation E apply to an electronic fund transfer that authorizes a financial institution to debit or credit a consumer's account. 12 CFR 1005.3(a). The term account means a demand deposit (checking), savings, or other consumer asset account (other than an occasional or incidental credit balance in a credit plan) held directly or indirectly by a financial institution and established primarily for personal, family, or household purposes. 12 CFR 1005.2(b)(1). It includes a prepaid account, as defined by Regulation E. 12 CFR 1005.2(b)(3)."

"Unauthorized EFTs include transfers initiated by a person who obtained a consumer’s access device through fraud or robbery and consumer transfers at an ATM that were induced by force."

"If your debit card or personal pin identification number (PIN) was lost or stolen, you must notify the bank within two business days after learning of the loss or theft. The bank cannot hold you responsible for more than the amount of any unauthorized transactions or $50, whichever is less. However, if you notify the bank after two business days, you could be responsible for up to $500 in unauthorized transactions."

Perhaps this is a little illuminating as to why your anti-fiat arguments fall on apparently deaf ears.

The simplest way in which crypto solves forex, at least in a narrow sense, is by the vendor accepting payment in a stablecoin, such as in one that matches the price of USD or EUR 1:1. Examples are USDT and DEUR. The transaction fees are very low, and there are no pumps and dumps. Swap fees between different stablecoins also are a lot lower than what a bank would charge as a forex fee. One is of course always free to…

It’s very unclear to me if you actually understood the discussion about forex fees. One does not “solve” forex by trading in a common shared currency, that is already possible without stablecoins - it’s just that vendors often want their local currency and therein lies the problem. Even if everyone moved to stable coins or Monopoly money, once you need to cash out in IRL, you encounter forex fees. A sort-of example i…

Cashing out crypto is a nightmare from a taxation pov. It's better to just spend it directly, and this is increasingly possible on online stores that accept it. I understand that this limits its use, but I project that these limits will keep diminishing as time passes.
