The only trick is, can he turn it into Bitcoin or other crypto. If the government is keeping him from doing that, there isn't much he can do. If he can buy Bitcoin, then he should do so before they stop people from doing so.
If this ATM is still there, I'd use it before it's taken down: http://greece.greekreporter.com/2015/07/10/the-first-2-way-bitcoin-atm-installed-in-greece/
Things are not going to get any better in Greece in the foreseeable future, IMO.
Yeah brilliant idea.. so instead of watching their Euro's turning to Ash they can use DASH to turn their cash to Ash even quicker. Promoting a shitcoin to new people so that you can cash out of your dying scam.. what a great bunch of crypto ambassadors you are.
If you were truly interested in helping people you'd promote Bitcoin in Greece, there are already Bitcoin ATMs set up there.
