Let's assuming someone would like to hide some money from the state and possibly earn something in return while keeping them immobile, also to beat inflation. Aside from buying "safe-haven assets" like gold, the only solution I can think of is buying cryptocurrencies. Is there any method that I'm overlooking?

T think there was some TV show about people investing millions into 'tax-paradises', basically placing money into a sort of black hole that only exists virtually where they don't have to pay any tax, typically in african country, but these types of things are illegal here. They made shitloads of money from it, even though its illegal.

Another thing would be if a country realised the night-watcher state, ie. a state where taxes are minuscule or non-existent. It would be either some form or anarcho-capitalist country or libertarian. But I think actually that Hong-Kong, before the chinese takeover, didnt have any taxes at all, and the country grew "over night" from being a poor shithole country into being a high-tech, rich metropolis with skyscrapers everywhere, when they implemented it.

Tax-havens are a thing, as you say. Several countries don't report information at all, which is why some BTC millionaires end up moving.
