For bitcoin to be used as a store of value and a medium of exchanging for goods and services, It must be stable like others currencies.
What stability? What "other" currencies? Fiat currencies? Fiat is the worst store of value.
This is the purchasing power of the U.S. Dollar from 1913 to 2013, and it is contantly sinking.
Give me Bitcoin, or give me death.
Well, when you made $20 a week it better have bought more.
The problem with bitcoin is it needs to gain value over time or it becomes irrelevant, who wants to hold your money in something that is sinking? fiat can sink over time in value and remain relevant because it's all relative to the other fiat currencies and wages, and bank interest offsets most if not all of the drop.
So far bitcoin has done that in spades, but if the next halving comes and goes and the price doesn't surpass the last high by a good amount within a year or so it may be abandoned and crash to near nothing. Leaving prior adopters stranded is not going to work.
