If you are living in the US, not homeless, getting paid US dollars via direct deposit, paying for your lattes with a Mastercard, then there's not much need for Bitcoin for you beyond 1) a speculative bet on it taking off globally. 2) a speculative hedge against the US dollar greatly losing value in the next decade.

But, if you are living in the confines of an backwards/broken/oppressive financial system, runnaway inflation, oppressive restrictions/sanctions, outright kleptocracy then Bitcoin is your sanctuary. It's complicated, risky, slow and tremendously better than what billions of people are dealing with from their local governments/banking systems.
