For me, Bitcoin has many advantages, one advantage is it gives to the individual money to sustain the basic needs, It also reduce the increasing number of unemployed in some countries, The people who work in bitcoin develops the ability to reason out, enhanced the English proficiency, that's the some advantage of bitcoin.
It seems to me that the main advantage of bitcoin it is still decentralized, not making money. To earn money you can do anywhere, bitcoin was not created for this.
Sure, decentralization made it possible for the other factors that can also be considered advantageous and so i think likewise that it is the main advantage of bitcoin that has provided us financial freedom from government regulation.
