I have about four different multi-wallets that I created with Trust Wallet, SafePal, and Metamask; one is just for altcoins and other cryptos, and the other three are just for bitcoin. I don't have any bitcoin wallets that haven't already been mentioned, and I'd like to know if it's possible to create a bitcoin-only wallet that doesn't require a desktop APP, works offline (because Windows wasn't purchased from a trusted party), and can be protected by a passcode or password. because I want to transfer all of my bitcoin holdings from my trust wallet to a more secure wallet that has higher security.
Read-only paper and hardware wallets are the best, but getting my hands on a hardware wallet now won't be fast or easy because of my location. Every piece of advice and suggestion will be highly appreciated.
