The issue is not much effort is put into developing price stability in cryptocurrencies, this is because it is counter to the incentives of the creators and early HODLers. They do not want price stability, they want significant price decreases, this causes people to speculate on the “currency” not use it as a currency. Until a cryptocurrency implements some form of MV=PY it will not really be successful as a currency.
How does one “implement” the equation for calculating GDP? All the (descriptive) variables in the equation are already present. IDK how that got 4 upvotes.
Several major cryptos are already used as media of exchange. That’s the actual criteria for “success of a currency”, relative usage. They haven’t overtaken USD, but let’s not pretend it’s just a speculative vessel, Ethereum sees over a million transactions per day.
You cannot, but you can increase money supply money supply more stably when following average GDP growth, and increase money supply more when velocity decreased- and atrophy the supply when it increases. And a currency is much more than just what people can spend at a store. It is what people keep their savings in, what companies pay their employees in, what banks lend.
This cannot be done with an unstable currency- you cannot have a debt that will either go up or down 20% in value in the same year. I do not think fiats are inherently more stable, but some fiats have proven to be somewhat more stable because of responsible central banking- its not a good idea to count on central banks being responsible for ever. But essentially all widely spread cryptos continue to have a significant amount held by speculators and therefore they cannot be stable currencies.
The simple answer is that fiats are only more stable because their relative worth is more settled. For the same reason small stocks are unstable while big blue chip stocks are (relatively) not. If you look at logarithmic charts of any big crypto over time you can literally see the volatility tapering out as the market cap increases.
