Bitcoin is a deflationary currency. I bought coins back in 2011 and 2012, those have now massively increased in value. I'm kind of a minimalist so I don't buy much, but if I wanted to, I could now go to bitcoinstore.com or whatever and have purchasing power many times what I put in. So the first question to ask yourself is maybe, could it be worth buying bitcoin, and save them for later. So instead of buying the exact number you need to purchase something today, buy 10 times more than you need, or 100 times. And keep the money there for the day you will actually need it.
Yeah that's the point upon which we agree, it's a thing that could boom. Thing that I can sell 100 of in 10 years and get myself maybe a nice flat? I want to believe in that becuse, hell, who does not want to be rich But otherwise its only USE that does not involve unnecessary hassle is silkroad. For all other uses there are traditional methods.
edit: and if you are using SR, it already does work for you, even though it doesn't satisfy all your needs yet.
