Put options are in max profit and call options are worthless. ETF is dissolved and individual stocks in the ETF are moving to OTC until the companies figure out whether to list.
Up 55% in 1 day? Classic bear market rally, however it has maintained it for 3 days so it may hang in there but I doubt it. My guess is it continues to get back to the 50-day SMA at $35 and it fizzles again. I saw an interview with the Krane Shares founder and he said he was transitioning from buying the US ADRs to buying directly on the Hong Kong exchange. That at least will get rid of 1 risk factor, however Didi was rejected for trying to list on the HK exchange.
