With USD, the government can print as much of it as they want. With BTC, nobody has that ability. What this means is that if you have USD as a result of your labor, someone else can print as much as they want, which robs you of your labor. Wealthy people know this very well, so they hold their value in businesses or real estate or other things that only the wealthy have access to, but absolutely not USD or other fiat currencies. Anyone can hold their labor in BTC, and nobody, not even the government, can print it privately to rob you of your value.
That alone is enough to make it an excellent currency, but it goes way beyond that. Anyone can send any amount of BTC to anyone else in the world instantly for almost no fee. BTC can be divided down as small as desired, making it useful for many things that USD isn't. The list goes on from there. This is why, a decade ago, when people were ridiculing btc as never being worth "real" money, so many intelligent people were able to predict just how useful and popular it would become.
Are you glad your tax dollars are paying for this?
