greenzilla... the cold truth is that fiat money, ergo, dollar euro etc.. are themselves virtual currencies. Governments mint "money" - it is just paper and metal that are representation of value. Value in itself does not exist like in the old days, where say 100 dollar would mean you had 100 dollars worth of gold in a safe somewhere, and a dollar bill would be proof of that. Long days are gone since gold as standard for value.
In essence, it is the belief that the USD/EUR has value that drives the markets. There is no inherent value to them. In fact, GOV can dictate, at will, how much money is actually worth through inflation manipulation.
For instance, China is inflating their money like crazy, on purpose, so they become super competitive in terms of mass production. Result is that it is cheaper to buy from China than to set up shop, say, a factory, in the USA. That is why the almost entire industrial strength of the US has vanished. But, they also creating a humungous bubble in the meantime with all this speculation.
Crypto currencies have absolutely ZERO centralized regulation, goes entirely by the blockchain's integrity (technical term, meaning ledger or total global accounting) - in essence, true financial tricks and crimes are not possible, nor its "value" be manipulated in the dark
Just like cannabis. They can try, but will never be able to regulate nature. IMHO Bitcoins, ergo, crypto currencies will boost the human civilization onto a new, more just society.
Fascinating times my friends...
