The only issue with these speculations is that only time and effort will tell. Yes, crypto is horribly volatile and only known to VERY few people worldwide.
It is the biggest opponent to central banking in the history of man. You cannot lie. Crypto will take massive massive effort for adoption, and seeing as law is controlled by banks, pushing for regulation will do nothing unless every government is trying to control it. If you gave the government a 90% stake in WDC they'd adopt it overnight. Since it distributed among thousands of users with the largest stake being 13.2%, government would not support it unless they control the majority of it. That is how every government operates.
Having a finite currency would KILL the credit and fiat scam in its tracks, something governments will not be willing to do, and something the people will have to choose.
How do we fight it? We really can't. When this system comes to a screeching halt, the people will be left with a choice as what they want the next monetary system to be. Crypto is not yet a store of labor, since gold and silver are heavily manipulated as well, neither are they. Both are better than fiat in my opinion so...
Anyways, these are my predictions (based on math and years of study, but take it as a grain of salt)
I live in the US (lol....'land of the free')
1. Taxes will continue to rise until even the high end working class can't afford anything. I currently pay 40% of my salary a year to taxes (this is including most everything including income tax) 51% of this country pays no taxes, which are the ones receiving the benefits ironically. Poor people hire no one.
2. The average American has $15k in just credit card debt, not counting loans, mortgages, etc. People cannot AFFORD to pay cash for most anything, unless they have a fantastic well paying career. Say I'm salaried at $63k a year. I'll only get $43k of this after income taxes, then I'm forced to pay sales tax, housing tax, service tax, convenience tax, etc. Taxes on everything but air.
2. The top 1% of wage earners here pay 68% of all federal tax income, none of which is used to run government. In the 1984 Grace Report, not a single NICKLE from taxes was used to run the government. It has all been credit since.
3. All of these taxes will increase to service JUST THE INTEREST on the national debt, which is over $18 TRILLION. Once they can't pay off this interest (kick the can down the road....) BOOM! Everything we fear comes to light.
To put this into perspective, the louisiana purchase (Thomas Jefferson doubled the size of the US with this purchase by the way) 45 Acres of land = 1 oz of silver.
We're in for a very rough road. Crypto is still chugging along and making massive massive leaps in innovation. 6 years ago, none of this existed. 2 years ago, WDC didn't exist.
Once again, this is a very very short telling of what's going on, and what I think is going to happen. Hold your faith ANYWHERE but the banks.
Mathematically it HAS to come to an end. It will. We don't know when.
