The situation over there (and potentially for what looms for other nations) is terrible, but I can hardly imagine citizens attempting to buy Bitcoin with their Euros. Surely it is getting access to the funds which is the problem in the first place.
Also I don't think that I would want to secure the majority of my wealth in Bitcoin, to even invest a significant portion I would need to full understand how I would go about procuring coin, and ensuring its safe deposit.
The fact that governments and banks allow for things like this to even come about is awful.
people should never invest the majority of their wealth in anything. 10% of your total balance for investing is more than enough. especially when it comes to highly volatile investments as bitcoin.
