One thing that kinda scares me about #bitcoin is the fact that you are your own bank. I mean, that kinda makes everyone vulnerable to criminals intruding your house? I’m not sure what to think about that.
Am I being dumb about this?

No, this is why you use non kyc services (so your btc buying adventures can never be leaked, shared or stolen by the nefarious) and you don't talk about your stack, making you a target for $5 dollar wrench attacks.
Further opsec could include multi signature keys to mitigate the wrench attack (being unable to transfer without a third party essentially) or keeping your seeds secured offsite
True. I totally get that. But more and more services HAVE to use KYC to comply with the law (in Europe at least). And then there’s the leak that happened with #ledger, leaking thousands of adresses online and what not.
Yep, these are all attack vectors that must be considered unfortunately. Seedsigner is good for this, as you can build a signing device with all parts from non nitcoin specific vendors, so no one need know you own one.
Seedsigner as a wallet?
It's a hardware wallet that is diy.
Correct, it is a stateless signing device, so it doesn't hold keys when it's not on (this is a security choice by design) , meaning you have to give it your keys each time you want to use it (either type them in or use a qr code you can create via their software). Also great for generating seeds in a completely offline way.
Makes me think. Is nostr:npub1sqzr42dj8vx32yd5jcvvl3ytux45kl0etgf6y2ymjvmd7lqmuwmqk9vk7v still non KYC?
Protect yourself from a $5 wrench attack with a geographically distributed multisig cold storage wallet. Use sparrow as a coordinator and store your private keys in different physical locations. Set up a watch only wallet to generate receive addresses. To spend, you generate a PSBT and physically carry it to each private key location for signing.
Can I dm you about that?
Only have enough spending Bitcoin available that you are comfortable having beat out of you.
