Yes it is. Money is anything widely accepted as a store of value, it exists in many forms such as currencies and commodities like dollars or gold. And since bitcoin is widely accepted currency so it is money.
Agree to this very clear explanation, since bitcoin can also accepted as a payment, that is already a form of a money. I can pay bills online because of bitcoin so it is also a form of money even if it is bitcoin as a 1st crypto-currencies around the world. Bitcoin is can be use worldwide and easy to use. Bitcoin has a value which is now $6000. So I can condiser bitcoin as a money.
Bitcoin is the best form of money in the world for me because you can secure your money because bitcoin can be a safe haven for our money and that will help the people in preserving their money and because of bitcoin they can pay things easily without too much hassle. If we will compare bitcoin to the current money that we have, there is no doubt that bitcoin will win.
