There's also a finite supply of it. There's a reason bitcoin transactions can be carried out to 8 decimal places.

Non-backed currency, like our current dollar, is susceptible to inflation when those in power won't stop printing it.

If we don't go back to a gold/silver backed dollar, I think Bitcoin would be a good replacement. When it first came out, it was pretty obvious to me, that it was supposed to replace traditional currency. Things went downhill when everyone started trading it for dollars.
