regarding the community's heated discussion about the 50 million USDT phishing attack, F2Pool co-founder Wang Chun tweeted, "Last year, I suspected that my private key was leaked. To confirm whether the address was really hacked, I transferred 500 bitcoins to that address. To my surprise, the hacker 'generously' only took 490 bitcoins, leaving me 10 bitcoins, enough for me to make a living."
