Yes bitcoin is the need of the day and is allowing mass to grow in a way they want. Bitcoin is helping people to get rid of unemployment to some extent and is helping them to earn good amount and make their living good. Countries will legalize bitcoin because they know that the running in the race without bitcoin is not possible. Bitcoin is going to replace all regular currencies in future for buying and selling of goods in daily life
