Bitcoin is more than a cult, for what it's worth. Bitcoin has value for rich Chinese to circumvent yuan capital export restrictions (https://www.scmp.com/economy/china-economy/article/3098981/c...), for Iran to sort-of bypass international sanctions (https://observers.france24.com/en/middle-east/20210203-in-ir...) and for North Korea to fund their nuke program (https://www.nasdaq.com/articles/un-says-north-korea-funded-n...).
In addition to that, it is a perfect tool for Western people to buy drugs, weapons and other contraband (Silk Road and its countless successors), for sending large sums of money across borders, and soon-ish to buy Tesla cars.
Basically, there are many people and governments with massive stakes in keeping Bitcoin operable and its dollar value somewhat high-ish.
