I want to increase my investments in Bitcoin, so I am interested to know the safest ways to keep the bitcoin stored here. Should I go with the hardware wallet, or are there any other safe storage choices available? What actions should I take to protect my Bitcoin from theft/ hackings?
Hardware Wallets (Ledger,Trezor) are the safest option for storing your Bitcoin, since they hide your keys offline and shield you from hacks.
