it is true that bitcoin can make someone the richest man in the world but it is also a risk because the whole network is base on the internet and no one can trace the money back to you.
I can easily say it is worth the risk but do not invest everything in it unless you have nothing else. bitcoin can sustain your life for the time being like nowadays market is good. what if the bubble burst then what will you do if you need money?

it is safe but risky and life is all about taking big risks so....
