BlockBeats News, December 21st, F2Pool co-founder Wang Chun commented on the recent "loss of 50 million USDT due to a phishing attack," saying, "It's really a pity. Last year, I suspected that my private key was leaked. To confirm if the address was indeed hacked, I transferred 500 bitcoins to that address. To my surprise, the hacker 'generously' only took 490 bitcoins and left me with 10 bitcoins, enough to make a living."
