Antwort auf: Ich wollte einen Ledger kaufen, aber jetzt bin ich unsicher.
At the moment, if you want BTC-only, Coldcard is the best on the market.
If you are storing anything other than BTC, the only real options in my mind are Ledger, Trezor, and the new Trezor.
Trezor has a known vulnerability, protected against by the use of a good passphrase (25th word). That adds complexity and risks of loss if you don’t manage the passphrase well, forget it, or don’t give an option for family to recover if you lose your memory.
Ledger has a vulnerability that you ultimately have to trust Ledger a bit. Not a lot, and it can be mitigated. Trezor too, but much less so. There’s no perfect security available.
Trezors new product looks very promising, but it’s not out and not battle tested yet.
At the moment Ledger is my pick for a lot of reasons.
Good luck.
