If there is one thing people love to be paid in, it is a collectible whose value widely varies daily based on when its larger holders game the system or when online drug markets get shutdown.
How does cash vary in value? If you have a $50 bill, you can expect to buy a very predictable amount of food (for example) next week, regardless of what happens. Not so much if you have 0.0521 BTC.
That's true, but most vary fluctuate wildly with respect to the USD, not in their purchasing power within their country of origin, even less so in the span of weeks or days.
For example, if I was paid the equivalent of a 50 USD ride in Bitcoin in Jan 4, and were to go to buy food today, I could only buy 40 dollars worth of food.
Which currency does that? Sure there may be a few examples in case of extreme inflation, etc, but it's not the norm at all.
Cash is liquid whereas Bitcoin is a collectible that can't be used to pay all debts. My last two points about Bitcoin's instability do not apply to cash. Cash doesn't have a few slow gatekeepers that also game the system in their favor when you go to convert your cash into a more liquid form.
Just a guess— because it's easier for LibreTaxi to implement as a free open-source project, without needing to deal with IRS, banking, & other financial bureaucracy.
That's great, as long as they do it in a way that allows both me and the driver not to have to wait an hour before the transaction gets confirmed. So either someone needs to shoulder that risk or those micropayment platforms on top of Bitcoin need to start making some headway.
