It seems that this market crash came from the seizure of more than 800 million dollars in Tether yesterday at the end of the day.
According to information, Bitfinex was drafted in this amount to cover a suspicious amount in its accounts. Bitfinex has already pronounced, via social networks, denying the information.
The big question that remains is one already raised by me before: is there deposited in the account of Tether Limited in Hong Kong, dollars equivalent to USDT issuance? I dont know.
Other important information: Among the 10 wallets with the highest balance in USDT, 2 are from Binance.
