In Lebanon, people are robbing banks to get their own money out. Maybe they are a little bit more comfortable than you are with holding keys to an unseizable asset.
If you live in the US and are hedging against the collapse of the FDIC you may be better served by investing in things like dried goods and seeds than cryptocurrencies.
Banking may well collapse in the US (I'm not betting it will - quite the opposite, to be honest - but historically speaking it's not an impossibility.)
The issue is that if banking in the US collapses... well - we have much, much bigger issues than "crypto". You'd be far better served with a stash of dried/canned products and a gun or three.
Also - it won't be crypto that matters in this case. It will be the new currency of whatever regional nation states pop up in the US after the collapse, or if the federal gov manages to hang on, the new USD.
Side note - last time I bought in bulk (because hedging against this is relatively cheap, all things considered) split peas were the best bang for the buck in terms of cost/calorie. Just slightly beating out plain white sugar.
75 days of food for 4 people at 2000 calories per day cost about $350 (not including storage containers) and will last a very long time if it's composed of dried legumes, flour, oats, sugar, rice, oil, etc... in airtight containers.
If you cook yourself and rotate through, it's actually a fairly cost effective way to eat cheap and healthy (although without any additional inputs - also very bland) while also keeping storage on hand and not feeling like a complete prepper.
