Hardware crypto wallets are a secure way to store your assets offline, as they're difficult to hack. But if you lose the wallet, the password, or the recovery phrase, it's bye-bye crypto
If am only interested in bitcoin then i see no reason why i should make use of a wallet that supports other cryptocurrencies, one of the best cold storage to go for is hardware wallet and i like the fact that you made mention of it here, you can also check out electrum multisig bitcoin wallet, but for maximum security measures, you can make use of bitcoincore, download and run abitcoin full node.
4. Bitcoin is legal tender in El Salvador
On Sept. 7, El Salvador became the first country to accept Bitcoin as legal tender. President Nayib Bukele announced the controversial move at Bitcoin Miami earlier this year. Bitcoin joins, but will not replace, the U.S. dollar as a form of payment in the country.
Bitcoin is not replacing the USD but rather work together in complement, they are both an acceptable means of making payments in El-Savador and a legal tender, Central African Republic was the second country to also announced it interest and make bitcoin a legal tender after El-Savador.
