I generally don't both evangelizing Bitcoin with merchants. Every human on the planet knows it exists and makes a conscious choice to not use it, even by inaction. You can lead a horse to water, but you can't make them drink.

However, whenever I'm stuck in one of those loops where I have to email both the merchant and the creditcard company to get their shit together, based on useless error messages along the lines of "computer says no", I do judge people.

Quietly.

Why do you choose to make your customer experience suck?
