If you want to move your pension – say to Sweden or Canada – you have to take a currency exchange hit UNLESS you use a cryptocurrency like Ethercoin. You need somebody in – say Canada or Sweden that you trust. Then you buy a tranch (don’t move your whole stash at once) of Ethercoin and transfer it to your buddy ASAP.
You have to be careful to report your foreign income on your taxes. But avoiding currency exchange hits is the only sane reason to use cryptocurrency.
