A kind of "Dragon Portfolio"
The original dragon portfolio is described here: https://docsend.com/view/taygkbn (very interesting read).
One could start with a more simple version, e.g. 20% crypto, 20% stocks, 20% precious metals, 20% real estate, 20% long volatility (VIX or similar), and the rest in cash... ;-) . Rebalanced only when the deviations from the original percentages become to strong.
