I am increasingly feeling that security is really linked to the size of your assets.

When the money isn't much, a hardware wallet is enough, at most copying the recovery phrase twice and hiding it well, and avoiding clicking on unfamiliar links out of curiosity.
Once it gets bigger, and you're frequently authorizing DeFi and playing with perpetuals, relying on just one hardware wallet makes me a bit nervous: multi-signature is more like "dividing the risk," but it’s also really troublesome, transferring funds requires gathering people or devices, and you'll curse yourself when you need money urgently.
Social recovery sounds great, suitable for those afraid of losing their seed phrase, but I’d be more concerned about "trusting who" and whether the recovery path can be exploited.
Anyway, right now I’m: running small hot wallets freely, while large amounts are kept cold and diversified, minimizing hassle.
L2 has been arguing about TPS/fees/subsidies every day lately, but I care more about: where you actually store your keys.
Don’t let the ecosystem get too hot, or if your account is lost, it’s all for nothing.
