So, yeah we can call it black market but I like the term “free market”.
https://en.m.wikipedia.org/wiki/Argentine_currency_controls_...
This automatically creates a “black market” of USD where the price is whatever the people are willing to pay, in the end the free market finds its way.
It is a market where prices are self regulated by supply and demand, without coercion. It perfectly suits for the exchange of of FIATs (or crypto) between parties.
You can call it whatever you want, anyways.
I recommend “Free to Choose” from Friedman as starting point.
"In a free market, the laws and forces of supply and demand are free from any intervention by a government or other authority other than those interventions which are made to prohibit market coercions. Examples of such prohibited market coercions include: economic privilege, monopolies, and artificial scarcities."
Further, a market in which fraudsters can commit fraud with impunity is also not a free market but a dysfunctional market.
At any rate, the notion of free market is only vaguely defined, as it's not an important theoretical construct in economics.
As far as crypto-currency markets are concerned, these are not a single market, but many different markets, some of which are heavily regulated, so it's hard to argue that it's a free market.
The cicle which I am most familiar with, goes by like this: gov destroys private enterprise and free economy thru regulations and expropriations, unemployment goes up and people gets dependent on hand outs, the remaining jobs bears all the costs. Unemployed sees gov are they gods, they will kept voting for them forever, even if they live in complete missery, it is all they have.
They become a “cyst”, it is very hard to go back.
You might think that any country controls their money supply, that’s a fact. But can Biden for example, double the monetary base with his sole signature?
People in those countries could have great aspirations, to have a fair system, a working democracy, a better government and all that… but don’t forget they also need to live in the meanwhile, while fixing all those problems.
I’m not a user of crypto currently, but I see it as a way of shifting power. Similar to what the internet did for information.
