If a stablecoin is backed by a central entity, you might as well hold it there.
I don't understand the point of keeping stablecoins that are capped by a bank on the hardware wallet.
the Ledger hardware wallet together with any other hardware wallet is the safest place to store your cryptos. But as private person only holding cryptos you don't pay tax in Germany if you hold them for a year.
Do you know if you got reported then by Revolut ? I just wonder what︃ came as an surprise to you in this thread with all the replies? Any EU︄ EMI/Neobank/Payment processor will have to report a company resident in the EU, and God knows︅ they do!
