Crypto is the safest in that sense for me, and a stablecoin is ironically more trustworthy than my country's currency in general.
Yet I don't trust USDT or UST so I'm on relatively more trustable USDC or BUSD.
Tether on the other hand has invested mostly in commercial credit, who’s counterparty they decline to identify. Given that they constitute something like the 5th largest commercial credit fund in the world on that basis & the other funds deny seeing them in their markets, it seems that they’re lending to ... lets say unorthodox counter parties.
Some have suggested that they’ve been lending to Chinese builders, but it seems more likely to me that they’ve been lending Tether to cryptocurrency trading houses and marking it up on their books. This would create a self-feeding circular dynamic at one or two removes; if so the whole thing could unwind quite spectacularly.
Long-term stability wise I think crypto will outperform gold anyway.
As a smart contract developer who knows a bit about the inner workings of crypto, I picked it.
But frankly yes gold would also be a good option. It has its own risks but safer than my country's currency for sure.
Converting back to cash at a reasonable rate is probably a lot harder.
(UK note: new gold is subject to VAT. Buy used.)
That does not mean that it is trivial to smuggle gold out, but if you need to do so, the chance of success is pretty high. Much higher than smuggling out fiat money held in a government-regulated account during capital controls. My 2c.
