If the global economy collapses, the first thing I do is cash out my BTC and buy a boat. I don’t trust any government or institution to protect me or my wealth. I would rather be self-reliant and independent on the open seas. BTC is great, but it is not the end-all and be-all of life. You need to have a balance between digital and physical assets, and be ready to adapt to any situation. I'd also stock up on food, water, ammo, and gold.
