The vast majority of the sheeple in western democracies have little need for crypto at the moment, although governments and banks are making it more and more attractive by the day - try paying $15,000 cash for a car, or sending that amount to anyone across a border. Everyone looks at you like you are a criminal. Indeed the entire financial education is slanted to that goal - that people with cash should be treated with suspicion.
In Argentina, where the currency is unstable, and movements of money in and out is controlled, restricted and unreliable, an alternative method of value transfer is a Godsend. There are shops in Argentina accepting crypto right now, today. This is short cutting through the banking and government bureaucracy and legislation.
And if you use DASH or Bitcoin cash, its almost instant. Bitcoin itself has become much faster. (And immediately you can see the transaction lodged and pending, even if it takes a few minutes to confirm).
In the USA, the idea of moving 10,000 into another currency, sending it, and then the recipient transferring out of crypto into fiat is awkward.
In Argentina, it is becoming the only way to do it. (And of course it is not just Argentina. )
As this method of value transfer increases in use, the users will start to keep more and more in the crypto, rather than immediately returning to fiat. Especially in unstable currency environments.
At the moment, if I were to sell a watch in Crypto, I set the price in USD, then the buyer pays the crpyto amount at that minute. As the transfer is almost instant, I can immediately move the crypto back into fiat if I choose - the market would have to be much wilder than it is today to be detrimental to the transaction. Bear in mind, that the buyer and seller can be in different jurisdictions, across borders, and have no compliance issues, and work in different fiat. So I can sell to someone in China, and get the money in minutes.
The big change will happen when prices are set in crypto, and proceeds are kept it in crypto. That is when fiat backed governments will react. But I think it will be too late.
For those of us lucky to live in a western democracy, we currently have (mostly) freedom of speech, and (sort of) freedom of movement. Imagine living in a controlled environment where the rulers know all your movements, communications, and control your assets. With a press of a button they can freeze a fiat account, or suspend your travel document. Why would they do that? Because they dont like what you say, they dont like where you send your money, or who you meet with. By the way, I just described the USA.
All bank accounts, while nominally allocated to account holders, contain money not owned by the account holders. It is owned by the government who issued it.
If you think the money in your account is yours, try spending it.
If you give it all to your daughter, you are taxed.
If you take it all out in cash, well you cannot.
If you want to send it all to a friend in Mexico, you cannot.
And if you do something the governments feel is contrary to some rules, they will freeze it.
So I say again. The money in your account is not yours to do with as you please.
I do not know where we are heading, but when it all starts changing, its going to go so fast our heads will spin.
