Well i would say that Dash was never really the king off all cryptos, because that always was and definitely still is Bitcoin and it will probably stay that way at least for a few more years. I would also say, that Dash was also never the King of altcoins because that is Ethereum. As far as i know, Dash was a pretty big project back in 2017 and 2018 and it was also during that time that Dash reached it's ATH of more than 1200$ per coin. Sadly for Dash it seems like privace focused crypto projects are just not in the focus of most crypto investors at the moment. That is also the reason why Dash was not able to reach it's ATH from 2018 in the bull run of 2020 and 2021. So i would say Dash is definitely not a king at the moment.
