I'd take my money off exchanges ASAP and simply get a desktop wallet like Electrum. Heard a lot of good things about Sparrow and Blue Wallet too, so choose the one you like more visually.
Make sure your device is clean of any malware. You don't want to move your coins into the hands of someone who's running remote desktop or a keylogger on your computer, right?
I would just get a Ledger Nano S plus if its BTC only you can get a ColdCard mk4 that is even better.
Holding on Ledger is pretty much like using a centralized exchange. It's a false feeling of safety. If you're looking for something cheap, Get Trezor One. It costs $60 or something like that.
Blockstream Jade is around $100. Both of these are better than Ledger.
