You're basically storing up funds instead of investing them back into the economy more or less hoping that everything else goes to hell.
BULLSHIT!
I invested all my money in my own successfull business. And I lost it all when government decided to grab it to repay national debt!
Read this. All my fiat assets invested to economy went to HELL!
Fuck EUR, fuck USD, I'm buying BTC right now! At least they cannot seize it.
Dude I'm sorry for your loss but first of all you will not lose your 720 000 unless that bank is a shady crap-bank (and in that case it's your fault) but you will just pay a small tax on it. On the topic you didn't invest your money but kept them in fiat currency which is just as bad as keeping them in bitcoins or gold or anything else.
Depending on what you do 820 000 isn't necessarily to much to have in currency so I can't blame you dude, I'm sorry for your loss
