The best way to do this is to keep your bitcoins offline.
A hot wallet is a pattern of bitcoin storage. The problem is that security is low and hackers are likely to intrude.
A cold wallet is another mode of bitcoin storage: a wallet that is not connected to the Internet. When users download a cold wallet, they need to download all the data from the beginning to the present, transfer the bitcoins, and disconnect the network.
The advantage is the security is high, the hacker cannot invade. But if the hardware of the cold wallet is damaged, the corresponding bitcoins will also face losses.
