Hardware wallets is the best option . I had always thought they were silly toys. Boy was I wrong. They are the Holy Grail of Bitcoin storage and use.There are three main hardware wallets worth looking at: Trezor, Keepkey, and Ledger Nano S. They all do the same basic thing, but in different ways. They create the cryptographic private key on the device itself. This takes all the concern about hacking and trojans away.
