How many years Bitcoin will need to become No.1 ?
I don't know that its rank is in 6th because i really think that bitcoin rank as the 1st largest currency world wide, may be for now when the market value decrease from almost $20000 to $7000 latest market price today.
I also wondering why bitcoin is not the number one highest currency. In my opinion, Bitcoin is the number one highest currency in the world because of its volatility in the market and it is also increasing its price time by time. Bitcoin is also adopted by many countries in the world and now accepting by many big companies in the world. Bitcoin will be the highest value in currency because it also legalized and used. It will deserve to be in the top at all times.
