and keystores can be stored online, such as cloud disk, or in their own U disk (hardware wallet takes advantage of this), which is relatively safer than online storage. Even if hackers steal your keystores, they can't steal the assets without the password of the keystores, so the password of the keystores is particularly important at this time

He distributed the stolen bitcoin in hundreds of network wallets, transferred it back and forth, and sold it at a low price on the trading platform after confirming its security. In this way, Dai has committed three crimes involving more than 20 million yuan.
