That's precisely what the New World Order wants: everything to be in digital currency controlled by a central bank. They want to eliminate any choice in the matter because if they control the money supply and have visibility into every account - they can literally control everything.

I can see the writing on the wall. The world will eventually be going to digital $. However if anyone thinks that the banking elites will allow any digital currency but their own may be dreaming. Maybe I'll stick to hard metal. They may try and devalue it but I'll take my chances. However that doesn't mean that I won't play the roulette wheel called the Market with the money I'm willing to lose just in the off chance I win a little.

You can also wallpaper with it, wipe with it, insulate a home with. it. Paper currency, fiat, I suppose, carries more value to you because you can see it. You have faith in the material good? With toilette paper average over a dollar a roll, perhaps we should start trading on the TP foundation.

Pull the plug and all this stuff disappears into the ether. It will live only in human memory and legend.

All true, but isn't the value of money (even gold and silver) based largely on whether or not someone else values it for trade? Don't get me wrong, I'd rather have something tangible. Just pointing out that one man's treasure is another man's garbage and vice-versa. Every monetary system begins with two people agreeing to use a currency of some type in lieu of payment in goods (barter). You are basically trading in an idea one way or the other...

Much of a coin's (non) value results from it being made of a lesser metal rather than gold or silver. +1

I'll be interested to see if anyone actually buys a cryptocurrency issued by a central bank out of choice. (You can bet that such a bank will seek to make such a currency legal tender in their respective nation!)

Interesting observation. Makes me wonder if an organization like the NSA already has such...

When supercomputers become more prevalent the security and integrity of those algorithms cryptocurrencies are valued on will plummet killing a cryptocurrencies value. And, who will own those supercomputers???

Yes, but you can hold paper money in your hand, hide it in a book or under your bed or bury it, or you can wipe your as with it. All cryptocurrency is smoke and mirrors. All cryptocurrancy can be filtered out through a myriad of routers, switches and firewalls (none of which you control). In otherwords, someone else determines if the bits and bytes have value AND whether you are even allowed to see or access it.

IMHO, any of these currencies are only worth what a bunch of people believe they are worth. Most currencies today are digital because they are held and accessed through a computer data base. Bank accounts, brokerage accounts, etc. are all in digital form. An online transaction is just that, whether the digital denomination is dollars, yen, or bitcoin. Bitcoin is worth more dollars now than before because a bunch of people (speculators?) have made it so and rest just go along with the game. It's all belief in the end unless something tangible is backing it up like gold, silver, or a Cabbage Patch doll.

Further, the value of the metal in metal coins is a fraction of what it says on the face.

Despite Bailey's objections, the Bank of England said in April that it would "join forces with the U.K. Treasury to consider creating its own central bank digital currency," Fortune reported.
