240 Days of Shock! 30,000 Virtual Currency Withdrawals Encountered Level One Freeze!!! On a deep night in July 2019, I sold some USDT at market price on a major platform. As soon as 3 arrived, my phone suddenly vibrated like it was electrified— all my bank cards instantly turned into "ice sculptures"! The freezing notice from Wuhan GA glaringly displayed "Level One Involved Case", and the uncle on the other end of the phone said the first thing that made my legs weak: "Prepare the materials, this matter is not simple." For the next 5 months, I lived like an external staff member of PCS, sorting out the entire set of on-chain transaction records, retrieving platform compliance transaction certificates, handwriting a 10-page situation explanation + letter of guarantee, until that rainy day in December when the uncle suddenly dropped a bomb: "The buyer is a gang of scammers, didn't you really know?" I swore on the spot to prove my innocence, and he stared at me for a full half minute: "... consider yourself lucky." On February 26, 2020, when the ATM screen finally displayed the balance, I squatted at the bank entrance with my bank card for half an hour— these 240 days taught me: the moment of virtual currency withdrawal is just the beginning of the real test.
