I started recording the "cost" of each time I use my private key/signature: the hassle level, the probability of making mistakes, and that uneasy feeling in my heart. After recording, I realized that as the asset size changes, the suitable solution also changes—small amounts just use a hardware wallet, don't complicate the process to the point where you find it annoying; when the amount increases a bit, multi-signature can really spread out the risk of "slipping up once and losing everything," but daily transfers will be slower; further up, social recovery is quite attractive, essentially turning "losing the seed phrase" from a horror story into a manageable incident, but you also need to trust those few people/institutions. Recently, everyone compares RWA, US bond yields, and on-chain yield products, but I care more about: no matter how good the returns are, if the signing system can't handle it, one authorization could mean negative returns… For now, I’ll keep recording, at least to help me avoid rashly choosing a solution.
