Wallet is the best choice among all cold wallets. Wallets are stored in cold wallets to protect customers' digital assets. And the key adopts the technology of multiple signatures and secondary verification of transfer, so even if the mobile phone is lost in sleep, digital currency will not be transferred away. Wallets also support multi-currency storage, which is very convenient for players to invest in different currencies. At the same time, the wallet supports the creation of multiple keys under one master key. This means that once the master key is known, other sub-keys can be generated. In order to ensure data security, the platform has professional technicians and a 24-hour real-time monitoring platform to ensure operational safety.
