Which hardware wallet supports the most altcoins? I am aware of Ledger and Trezor. What are some other hardware wallets which I can check out?
Most hardware wallets just list bunch of worthless tokens to pump their numbers for supported coins.
Ledger supports 1250+ coin, Trezor supports around 1631 coins, Bitbox supports 1500+, etc.
Check out list of all hardware wallets and double check on their websites:

Ledger Live is native application made by Ledger but you can use those non-supported coins with other wallets, for example Monero works only with their wallets like Monero CLI, Monero GUI, Monerujo and Feather wallet.
You can even use Ledger wallet with Electrum wallet for Bitcoin, and not even use Ledger Live app at all.
