I remember JamesWynn when he always posts his position with a x40 leverage. I mean it work for him for a moment, and made huge money, but overtime, he lost, and lost, and lost. Right now, I don't have any updates about him anymore with regards to his positions.
After his deep regret on social media and after he deactivated his X account, he later reactivated it back and also open positions again. tvplus006 talked about it

25x leverage is too much and I think it will be used by only greedy traders.
