The only people I know using hardware wallets are the ones who never do transactions of bigger values in real life. You don't need a hardware wallet, any piece of paper with you account keys is safer than whatever that "ledger" ever was. Don't keep your funds all inside the same wallet. There are app like CoinMarketCap that permit to keep track of funds on multiple wallets without access to private keys (you have to manually set it up) but helps to keep track of the overall value.
