Binance deferred Quarkchain's listing for almost a day. Before that, all investors (most of them) started their tokens on Binance. And what happened? Trade began everywhere, and Binance said - "Sorry, we've changed our mind, wait for the news." Investors could not get the Quarkchain tokens from the stock exchange, some chaos began. After 16 hours, Binance still made an announcement and then in 24 h. launched a trade.
But, one big BUT! The moment was missed, a big price increase did not happen. X13 is nothing compared to what was expected and what kind of testing circles had to be passed all investors.
I don't understand why you write about delisting? This Binance must give back the money to Quarkchain because of the delay in the listing. They did not fulfill the promised conditions.
