Why limit your choices to only these specific assets from a "currency" class? Why not include other cryptocurrencies and fiat? And of what value is hindsight here anyway? The other mistake that's typically made though and I could have expanded on this earlier in my post is in comparison of different "currencies" whereas each have different attributes. BTC for example as you note appears to be deflationary with respect to fiat currencies which are inflationary by design and policy. On the other hand I can't buy groceries with BTC so I would have died during the pandemic and Dollar and Euro would have been superior choices.
