Hm, idk, you are Kind of right, but i do recommend seedsigner to everyone. As you Said there is No way around doing the Work and learning the Shit. The sooner you do it the better. Seedsigner greatly helps with the learning curve. So i think it is quite Important to recommend seedsigner as much as i can. Regular commercial Hardware Wallets do Not Help you learning stuff. And they will wreck you sooner or later, because they all have single Points of failures, speaking of their centralized Servers, which are honeypots for CIA, Lazarus and WHO Else.
