Bitcoins will never fit Banks standards
, jokes apart they're really a menace for a golbal economy based on currency control.
Menace to banks, perhaps. To global economy, no. Anything that has the potential to remove barriers to the exchange of goods and services can lead to positive disruption. Banks and governments find the idea of digital currency threatening because it's more difficult (not impossible) to tax and control across borders. But that's also where much of its potential lies. Anything that allows me to more easily do business across international borders should in theory actually lead to greater, not less, economic efficiency.
