Well, the only thing better about cryptos is that they cannot be easily inflated (accept for that bankster-like coin) They have rules that are easily known, and accounting is almost automatic.

Transparency is the most essential feature.

It will allow the future generations to see where things are failing.
Bank prints money (but no one sees it) prices go up, (people see that) and then people blame the businesses. Its because they cannot see that first step. And, it is well hidden for a reason.

After we have transparency, then we can start working on creating a currency that works. All money should be based on labor. But not any kind of labor, but labor that others find beneficial to society.

So if I make a widget, it has no value until I sell it. We could, instead of selling it for cryptos, we could create the cryptos at the time of sale, because that is where the value was actually created. Then those cryptos should be extinguished when I go and exchange it for something else, that I give value to.

It will happen. Hey, cryptos have only been with us a decade.
