A commonly used hot wallet, two 5.49usdt were inexplicably transferred to an address a few days ago. It is very strange. If the private key is lost, why not just transfer all the tokens; if it is unlimited authorization from the contract, why just transfer it away? 10.98 US dollars, there are still dozens of #usdt left that haven’t been transferred? Safety is really an issue that cannot be addressed too much, whether you are a novice or a veteran. Maybe you were tricked before, but because there was no money in your wallet, the hackers didn't take action. When the time comes, all the hard work in a bull market will become someone else's wedding dress.
