A popular sentiment here, but not a responsible one to take literally.
Different classes of assets have different vulnerabilities and different advantages. The "portfolio effect" refers to the way one can avoid getting rekt by investing in different things, ideally with low correlation between risks ("gamma").
Skills, tools, BTC, XMR, precious metals, real estate, a seed bank and fiat instruments all have different qualities.
Bitcoin enters a death-spiral of forks and institutional capture? Would be infuriating, but if you have the other asset classes you won't go hungry.
