Perhaps a Hardware Wallet like SafePal could be cheaper.

This has nothing to do with a HWW, rather a mobile gateway to Bitcoin & other services that focuses on keeping my sensitive data safe at the expense of connectivity & day to day internet usage.
Also, if I could offer you some friendly advice;
I would buy a better HWW than that one to store a substantial amount of bitcoins.
Something that focuses only on Bitcoin & runs free & open source software would be ideal.
Once I thought that if I were a millionaire with #Bitcoins I would distribute my fortune among several Smartphones, each one would have... I don't know, maybe around 10k USD equivalent in #BTC. This reduces the risk of losing everything at once But here I am, I'm still poor and I only have enough for the Smartphone I'm using 😅
Hah well I wish you luck on stacking your Bitcoin to ever greater heights 🫡
Jade from Blockstream is btc only, pretty reputable, and the most affordable of the bunch.

Seedsigner project is pretty solid against all internet threats, and a fun diy.
Golden grail then eventually would be a multisig, where you combine then + a mobile wallet or a Tapsigner..
