I wanted to check upon your experiences with these two devices. I already ordered the Onekey Classic so i guess will use that for a while. But was more interested on your thoughts about these, will use them for BTC and to crosschain swap between BTC and USDT on different times, instead on dealing with CEX's.
OneKey is biggest hardware wallet manufacturer from China and they are very popular there, but they mostly cloned code from Trezor.
From my own experience after talking with them about working together on one project, I can say they are semi-amateurs and liars.
I can't seak much about quality of Onekey wallets, but I know they had serious bug connected with secure element, and I wouldn't really use any Onekey device as a main hardware wallet.
Bitbox is Swiss made and they are more professional but small team so don't expect miracles from them, and I think they also started with Trezor code.
I would rather choose Trezor 3 Safe original wallet, instead of both options you mentioned.
