Specifically, the cold wallet stores your private key in the form of no Internet connection to ensure that hackers do not steal it. Computers, mobile phones and USB flash drives that are not connected to the Internet can be called cold wallets, or even buy a small book for a few yuan to manually record the private key. This book is called cold wallets. On the contrary, the hot wallet stores the private key in the form of online networking. If the operation is not careful, the probability of losing it is much higher than that of the cold wallet. Hackers steal digital assets from time to time.
