Maybe someday bitcoin or some other crypto/block chain will replace fiat money and central banks, but for now it seems like a pyramid franchise. Some people made a killing and sold out for good ole greenbacks.
Bitcoin? Mt Gox and many other embezzlements. FBI seizing e-money as part of anti-criminal raids. Vladimir Putin supports Etherium. Spare electricity generation in China used to mine Bitcoin? It will work as part of institutional transfers ... but not for the public. This isn't a game changer at that level.
If you have very verifiable money transfers, governments like that, not that will stop money laundering, because the governments are the chief money laundromat. But it gives them better control over organized crime (which works for them). Real Mafiosi settle accounts by trading stolen Old Masters, or with bullets ... no transparency.
The data format is a chain of non-deniable encrypted book entries that go back to the Creation. That gets unwieldy with a trillion consumer transactions per day. Just like the Internet-of-Things (small packets) requires infinite bandwidth. Universal e-currency (with every packet getting constantly larger) also requires unlimited storage and processing power.
