Bitcoin is so expensive if it will be converted to my country's currency it will cost hundred of thousands.
Why bitcoin worth that much even its only a cryptocurrency can someone give me an idea.
Since Bitcoin is decentralized and not governed by any one country, its not susceptible to major changes in valuation should a country do something that could make their money less valuable. Many people are using the cryptocurrency to keep their money safe from devaluation, or even to use it as they would paper money.
