What’s the Worst that can Happen?

I’ve recently debated with my spouse on whether or not I should put 100% of my net worth in Bitcoin. It’s already a higher percentage than we initially planned because we bought the dip (thanks Sam). I cannot wrap my head around how governments, banks, and corporations holding lots of cash and bonds can be solvent or perceived solvent in a war era already struggling from inflation. Are there any realistic scenarios, not quantum, where bitcoin could go to zero?
