I know its a bit boring and it's never going to go nuts like cryptos, but ultimately gold bought using cryptos from gains made on cryptos is truly anonymous and will hold its value whatever happens to economies, cryptos, and laws.
So it's insurance. While cryptos go up gold won't. And vice versa!
Truth is I couldn't trade cryptos with full confidence if I thought I could lose the lot. Having 10% as gold means I can't ever lose the lot, so I can gamble the rest.
And Bitcoin I've made big gains on, sold and moved on from.
Can you buy gold directly with crypto?
