The cranks on my bmx keep on getting loose after 1 day of riding, I tighten them fairly tight but then 1 – 3 days later the become just as loose as this picture. And then i have to tighten them again. How do I prevent them from doing this? It doesn’t matter how hard I tighten them they always becomes loose. Both cranks gets loose btw.

Maybe try locktite?
Make sure the cranks are on the right side and tighten the axle bolt first and then the pinch bolts
Hey my dude, bmx’s are especially susceptible to bolts coming loose because they are rigid and all the force and rattling just wiggles things loose after a while. It’s a good practice to do a quick nut and bolt check every once in a while. Critical ones are wheel nuts, crank bolts, and handbar/stem bolts. 4,5,6,8 mm Allen keys should get you most of the way there 🤘 keep riding and having fun
