2015, Bitcoin was trading at a price of about $400. Soon, a strange paradox emerged. Bitcoin came to be seen not as a medium of exchange but as a store of value—digital gold. People put their savings in it, and investors bet on its price; there are even financial products linked to its price (

euro exchange rate does fluctuate from day to day, even minute to minute. But the volatility is limited.

none of these protocols can do much to address one of the fundamental deficiencies in their supporting roles in creating a reliable medium of exchange—the instability of the cryptocurrency’s value relative to the unit of account, which is typically a fiat currency.

by parceling out the various functions, cryptocurrencies have already changed the nature of money.
