This is why cryptocurrency is not getting anywhere. What is the point of legislators doing loads of work to get a payment method on the books, as in Ohio, if only 10 businesses bother to use it?
We're going backwards partly because people are hoarding their cryptocurrency instead of using it.
I think it's really coz of the speculation. Even if the value of the bitcoin to be paid in taxes is the same as what would have been paid in fiat, people feel they're losing the opportunity to make more money out of it so they'd rather just plain with USD.
I for example can pay my bills online with bitcoin but I prefer only doing it when the exchange rate is high, else I just pay with cash (no auto-deduct for me).
