bitcoin is very volatile, such high volatility becomes a major barrier for merchants to accept bitcoin as a means of payments.

Imagine that in December 2017, some merchant accepted bitcoin as a means of payment, the merchant would be selling a car for $100,000, if in December 2017 someone had bought this car that costs $100,000, that person would have paid with 5 BTC and if that  car salesman  Hold the 5 BTCs, how much losses should he have these days?

Current bitcoin price:

1 BTC = $ 3560

5 BTC = $ 17,800

merchants will be afraid of this volatility

Bitcoin has not been legalized in many countries, so it would be difficult to have many merchants accepting bitcoin as a means of payment
