Hi, I would like to upgrade from my ledger S to a new bitbox.
I'm no technical wizard by any stretch of the imagination, but from what I've heard from members here any device with a secure element (including the Bitbox wallets) is subject to the same problems Ledger revealed to the world--and all of you who do understand the machinations of key exfiltration by HW wallet manufacturers please correct me if I'm wrong. However, I'd trust Bitbox over Ledger any day of the week, and if you've got to use a HW wallet the Bitbox02 isn't a bad one at all. Whatever you decide, my advice--which you already seem to be leaning toward--is to ditch Ledger ASAP. I'm sure I'm not alone in thinking they're a ticking time bomb just waiting to go off.
The only two problems I have with Bitbox is their UI (which you don't have to use) and the device itself which is more cumbersome to use than a Ledger, at least for a fat-fingered fumblebum like myself. If you're not doing a lot of sending/checking balances/etc., it probably won't matter much to you. Good luck, and fuck Ledger!
