If asked to me why bitcoin is very valuable compared to other cryptocurrency or gold. To be honest, I can't either give a strong reason,
but in my hunch the possibility of bitcoin is the first cryptocurrency. Become better known and trusted, then bitcoin is also purely
decentralized. This might make bitcoin demand high, and become a symbol of resistance to monopoly paper money. Therefore bitcoin
has fanatical supporters in my opinion.
Its really simple. People in this digital age wanted a online currency controlled with math as law with a ever growing worth. You used to be able to buy a loaf of bread for 10cent usd or a coke for a nickel right.. well now every year the cost of things increases and your dollar decreases in value. Everyone is taking a cut off your dollar too.
Any governments cash is kinda a wildcard currency when you think about how cash works and how its made by a specific one government. Bitcoin is like the whole worlds online currency, and you dont have to put it in your pocket, get out of a atm or place in a physical place that takes up space. Technically it should be better on the environment vs random metals and paper with toxic elements.
There is also fake cash floating around, there is no fake BTC.
Although now Bitcoin (BTC) is harder to get and more of a asset. Its also taking computer parts and electricity to manage. It takes effort, work and your own equipment to help manage the calculations to run Bitcoin so you get paid some Bitcoin for running the hardware so its also worth something because people are putting “worth” in to the system to get “worth” in the form of BTC for their service. Since it was created in 2009 its taken years for the worth and adaption of bitcoin to grow.
