Any Greeks who'd put their capital in a safe place have already done so by now.
Yes, but more money is constantly being generated by economic activity (tourism/agriculture) and financialization (EU QE/loans).
That new money needs to be put in safe place. The problem with using Bitcoin to avoid capital controls is traceability.
Greeks (and the rest of us) should be looking into Monero, Bitcoin's anonymous/private little sister.
Thanks to the new site xmr.to you can spend it anywhere that takes BTC.
