Cold Wallet. Fully Airgapped. Never record your key anywhere that can be accessed from any computer.. and don't even keep it anywhere where it is accessible. If you more than a small amount robberies could target you by forcing you to unlock and transfer at gunpoint, torture, etc... but that could happen with any bank account or gold or silver or whatever too. Just gotta be careful in that case.

That said. It totally sucks to lose that much money. I'm sorry for your loss. It can happen to anyone if someone wants it bad enough and knows you have it.
