Safe cryptocurrency storage is one of the most important issues for every trader. Many cryptocurrency exchanges offer built-in ‘hot’ online wallets. They are considered more agile and reliable for exchanging transactions, but remain more vulnerable to hacking as they are connected to the Internet. Keeping bitcoins offline reduces the threat of cyber attacks. As a result, some bitcoin traders prefer storing their coins in cold offline wallets. They represent hardware devices, which work in conjunction with compatible software but can’t be compromised as they have no internet connection.Many bitcoin holders use both wallet types. They keep some crypto assets for regular transactions and spending in a hot-wallet, but store the rest in a cold offline wallet for safety.
