Hardware Wallet vs. ETF

Is anyone splitting their stack between their Hardware Wallet and an ETF?

This seems like it could be a good risk management strategy. If your hardware wallet is compromised for any reason then you would still have the other half of BTC.

I know the chance of a hack is slim to none but there are multiple reports of it happening to people on reddit–probably due to user error, of course. However, we can all make mistakes or accidentally expose ourselves to risk despite our best efforts.

I am seriously considering doing this for added peace of mind. How do ya'll feel about this approach?
