According to @EmberCN, ByBit and FTX exchanged platform tokens in early November 2021: ByBit swapped 100 million BIT for 3.36 million FTT from FTX, with a mutual agreement not to sell for three years. This lock-up period will end in two months, and a sell-off is likely. At the time of the swap, the exchange was equal in value, but now there is a significant disparity: 100 million BIT is valued at $57.73 million, while 3.36 million FTT is worth significantly less.
