Your question is why I hold bullion (all shapes and sizes) over BTC. I have hard-drives from over 20 years ago but what I created then (e.g. manuscripts for hard-copy books) has diminished value in today's content platforms (tweets, tick-tocks etc). It will take hope and partisan persistence to ensure your platforms and exchanges survive the next 15 years, knowing THEY will come after you in all shapes and forms. Don't give up bitcoiners.
