In a stable economy like the USA, companies are not PRICING products in bitcoin, they are converting to USD at the moment of sale.
Have you bought anything in USD lately? Literally every time I go to the supermarket or go to get gas, the prices have all gone up again. USD is simply too unstable to price products in; vendors are obviously pricing based on the value of the goods and services they need to buy and converting to USD.
There are MUCH BETTER, less risky investments than Bitcoin.
If you could go ahead a provide a list of these much better investments which have outperformed bitcoin over the last 10 years, that would be great.
