How can Bitcoin save you from being poor, and how is it the people's power? You have to explain what you mean. 

Bitcoin cannot save anyone from being poor, but rather, as an individual, you can save yourself from being poor by not doing things that can lead to your poverty. An addict to gambling, a reckless spender, and other factors can make someone poor. If you don't want to be poor, then don't do those things mentioned above. Bitcoin is not a get-rich-quick scheme, but it can actually help someone build their income. But that's not enough reason to say that Bitcoin can save you from being poor. 

I can't make anything out of the second point where you said it's power.

@OP, Bitcoin is popular for so many reasons that have already been mentioned by other people, but one simple reason for its popularity is that it is the head of all other coins.
