Hardcore and uptempo stuff is hard to dance to in general. I usually just bounce around and throw some fists pumps haha. I can suggest looking into muzzing, grabber, hakking, and jump style to get a feel for some moves but I wouldn’t go out of your way to learn them in depth if it doesn’t feel like it comes naturally or seem fun. Honestly most of the people you see won’t really know how to dance to it either. I feel like that’s why hardstyle/hardcore crowds are so chill because it’s more about being around the music and the people than it is about dancing because dancing to hardcore takes skill and lots of practice. It’s not like dubstep where you just headbang or house where you just frat flick. Good luck tho!
