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.
i believe he was talking about other currencies aka fiat like USD,JPY,CNY and many more.
also, that 'thing' is much more stable compared to Bitcoin if we are looking at its history.
USD lost 96% its power in 2013 from 1913, but it needed 90 years to do that while Bitcoin only need a few months. that means USD is much more 'stable' compared to Bitcoin.
