That is right, no one ever buys nor sells anything in Bitcoin

Some stores that claim to " accept " bitcoin are just providing a quick and easy way for you to convert your Bitcoin into US DOLLARS, which is what the store gets. All pricing is done in US DOLLARS, and the store deposits into the bank and operates in US Dollars SERIOUSLY, could you imagine trying to run a store, and price something in Bitcoin

If you are still to dumb to get it read a few examples below:
If I were looking at car's, a they were advertising selling a Toyota Camry for 3 Bitcoins, one day it would be a total bargain, the next day a fair buy, and the next day it might be massively overpriced.
Would you rent an apartment that really operated on Bitcoin, priced your lease in Bitcoin of 1/2 bitcoin per month

That would have been great at the beginning of the year, and you would be evicted and homeless now as the price more than doubled.
How about get your salary paid by BitCoin, lets say in January 2018 you took a salary of 1/10 bitcoin per month. You would be working for almost nothing a year later.
WISE UP PEOPLE, realize the difference between using bitcoin as a currency, and converting it t US Dollars to use as a currency 🙈🙈🙈🙈
Thats really interesting fact. The main reason for this is bitcoin price volatility. Bitcoin is still valued in US dollar and its own value is yet to come. Things like house rent in bitcoin can be materialized if we have a stable bitcoin who has value independent of US dollar.
