You cant see price data without creating an account that requires a social security number and government ID, which is a bit suspicious. Looking at a different, larger exchange, I see virtually no action to be had at high strike prices: https://www.deribit.com/main#/options?tab=BTC-25DEC20
Call it suspicious or whatever you want, but they are licensed in the US. My experience with their platform is that cater to much more passive investors than the typical crypto exchange. For example, people who want to hodl but sell some OTM calls to generate income from their holdings.
