Bitcoin was first developed to be used in marketplace and shops. It is to make transactions easy for us as third might not be need in exchange for good and services transactions. However currently we are using it at investing tools just like stocks and commodities.
I consider bitcoin to be very practical for payment transactions, even though it is online and between countries because it is peer to peer and eliminates the role of banking.
But naturally bitcoin is also very suitable as an investment, both short and long term. This proof has taken place and has been enjoyed by many people throughout the world.
