The talks about FEDcoin has been doing the rounds since 2014. The purpose of FEDcoin would be quite simple, digital tokens of dollars, replace cash, enforce a complete centralized privacy-less cryptocurrency upon the masses. It's likely that the Federal Reserve might attempt to come up with something like FEDcoin, the last arrow in its money quiver, but for it to gain any mass acceptance, people would have to choose it because there isn't any other choice/no alternatives and precisely for something like that to happen the whole decentralized crypto market should be non-existent. Do you see something like that happening anytime soon? No.
In his prediction Doug Casey talks about the Fed making sure that Americans actually use this cryptodollar. As I got, it means that the use of this coin will be obligatory. For example, they could force you to pay taxes with it. And that's the whole idea behind it! If we separate the wheat from the chaff here, in essence, it all boils down to creating a new dollar and then possibly declaring the old dollar no longer legal and valid in the US. The rumors of such development have been circulating for at least a decade.
because what is the difference between that and the US dollar? Nothing they are both private currencies that are backed by private individuals. It won't help the world one bit and I pray to god nobody falls for that scam of a coin.
