Storing bitcoin safely needs to happen offline, on a device called a hardware wallet. We call this cold storage.
Anything stored online can relatively easily be hacked. Storing your bitcoin on a hardware wallet, detached from the internet, is the single most important thing to do after buying bitcoin.
Hot simply means connected to the internet, like your phone. Cold devices are not connected to the internet, like a USB stick.
There are dozens of hardware wallet options. We have tried and tested a wide variety and found that most are secure but also hard to use. Bitsaga sells three hardware wallets with a strong focus on being easy to use and bitcoin-only. Being bitcoin-only strongly reduces the attack surface of a hardware wallet, making it simpler and safer.

Triple your security with multi-sig
When storing larger amounts of bitcoin, a wallet protected by a single seed has two problems: it is a single point of failure, and it has zero fault tolerance. Lose that seed and you lose your bitcoin.
Multi-sig wallets can use multiple seeds, for example three, and require multiple signatures, for example two, to solve this elegantly. You no longer have a single point of failure, since you can lose one seed and still keep full access to your bitcoin.
Bitsaga personally guides you through setting up a complete multi-sig wallet suited to your use case, so you no longer have to worry about your bitcoin.
