That depends how you obtained the crypto in the first place.

In any case, its certainly better than visa, but if you dont trust your vpn provider the real issue is they have your IP address and at best just a pinky-promise they dont log.

They can find your wallet, but if your wallet is not linked to you in an obvious way...

I went in on Monero (which Mullvad accepts for now...)the only early crypto that had a viable usage plan from the beginning. That was of course before I realized that crypto would of course just be turned into a massive scam wheelhouse and any coin with real utility value to challenge fiat currency would of course be regulated against. (not salt its still worth a lot)

I am aware most crypto is not anon without extra effort.

Not all digital currencies work that way.

They accept Monero too

Depending on crypto, and even on public ledger ones, there are ways to on-ramp cash to a new cold wallet.
