**2019**

- [3396522-038](https://wulfkaal.github.io/claims/3396522-038) [mechanism/argued] -- Merchant adoption of stable cryptocurrencies turns on a concrete threshold: merchants pay 2.9 percent to credit card companies on non cash transactions, so any medium of exchange costing less than 2.9 percent benefits merchants, who can pass the saving to consumers as a discount.
  > In the existing digital commerce, merchants pay 2.9% to the credit card company for any transaction involving non-cash transfer with credit cards. Merchants would benefit from any medium of exchange that requires them to pay less than that 2.9%.

**2024**

- [4734750-039](https://wulfkaal.github.io/claims/4734750-039) [failure/argued] *(failure mode)* -- Intermediary payment fees on centralized micro task platforms are economically viable only for high volume workers who can eventually avoid them, so those fees function as a barrier to entry for new micro task workers.
  > The fees in centralized mechanical turk platforms are only economically viable for higher volume workers who can at some point avoid the Paypal fees but create barriers to entry for new micro task workers.
