May I ask, where are you from? Given your nickname and english I suspect you are from the US or UK. I'm from Brazil, in the 80's and 90's Brazil had over 6 currencies. All of them went to zero, the government also had capital controls so it was hard to buy dollars to protect savings.
The only reason some people were able to keep some of their savings is because some of them bought real estate. Stocks dropped 95% in real terms so they were no haven. For people like me, its beyond obvious the utility, its limited in supply and government cannot prevent people from buying (just like they cant prevent people from downloading movies or series on Bittorent, a peer to peer network). BTC can also be sent to anywhere in the world if you have a computer, unless government shuts down the internet they cannot stop it. So it cannot be inflated, it cannot be capital controlled. Its the ultimate monetary fuck you to the government, and some people wonder why its so valuable? That's the utility, your savings no longer depend on governments doing the right thing. And it comes with a payment system on top of it.
Had you been born in Argentina you would have understood bitcoin much earlier, but if you grow up with 2% inflation every year, yeah, it doesnt seem to make sense. But the world is a big place and financial risks are higher than ever before, even in major developed economies....
Some food for thought
