Many people are confused of Bitcoin and mostly mother's having double mindset of what bitcoin can buy. But i wasn't bias on the question because i know that Bitcoin is a digital currency and it can buy things for the country that approve it as a legal tender, and with Bitcoin profit you can buy things for shop's that accepts bitcoin for monetary transaction's. So i want to ask this question generally so that i will have more insight of what bitcoin can buy using Bitcoin without converting to fiat currency before making purchase.
It's great that you're excited to see people using Bitcoin to buy and sell directly. But we need both Bitcoin and fiat money to run. People have been using fiat money for ages, everyone is more than used to it. So you cannot remove fiat money in one fell swoop.
Moreover, volatility remains the same, to avoid this problem you should always use a stable currency that is backed by fiat currency. Mass adoption of Bitcoin is possible only if a balance between fiat money and Bitcoin can be maintained.
The removal of fiat currency is not the main issue but the vast adoption of Bitcoin is an important issue, and we should focus on it, good thing is many countries have now added Bitcoin as a payment option.
