Recently, the market has been good, and some friends who have not been exposed to cryptocurrencies are starting to get restless. Here I remind you again, the most important thing in the crypto world is security! Security! Security! So the question arises, how should individual investors store cryptocurrencies? Three types of wallets: hardware, software, cold wallets 1. Hardware wallet A special 'U-shield' used to store private keys, not connected to the internet, with transaction signatures completed on the device. Advantages: Private keys stored offline, very high security. Disadvantages: Buying devices costs money, each transfer requires plugging in the device and entering a PIN, not suitable for high-frequency trading.
