BTC is nice tech on the paper (solving the consensus problem in a decentralised way) but it's kinda slow and unpractical for real world usage. If it's meant to be used only by some banks while you do other transactions off chains - then you reintroduce trust and lose the benefits. The value is all baseless speculation and hoping a central government won't class it as illegal once they get to do their own "crypto" to control their citizens better. The main value in BTC is that it's at the moment less regulated than the financial mess we have in the standard market. I think a better model would be to have tons of small private banks without a central banks and use a currency 100% backed by a basket of goods of prime necessity (wood, wheat, iron, gold). That said, I hope will somehow they will succeed in replacing central banks and I hope some of the revolutionaries who got rich with crypto will topple governments and create a decentralised society without (or better - with less) central points of failures.
