“Most important part” is subjective here. 

With a handle like mine, the most important part is its provable scarcity. 

For the person in Argentina and Venezuela, its freedom from insane inflation rates.

For the ex-NSA agent in Russia, it’s censorship resistant to being financially destroyed and cut off from transacting with others. 

For the father of three whose wife is cheating on him, the father no longer has to give up half of his assets anymore when they divorce.

For the energy companies, Bitcoin means that there’s no such thing as “stranded” energy. 

It’s all subjective, but what isn’t subjective is that it is speech.
