No wonder. The last tweets from SBF has been lies. In particular he's stated that Alameda Research would stop trading on FTX. This is glossing over the fact that Alameda Research is a major liquidity provider for FTX, meaning that if they stop trading there, there will be no party to take the other side of trades anymore. With a completely illiquid exchange, trading becomes all but impossible and you risk extreme slippage as a consequence of it.
