That person was really brave to use 25x leverage... maybe he hoped that with a long position the price would go up, but instead it went down, resulting in rapid liquidation.
I am not new to trading is the reason I will say the person is not brave at all. There is difference between someone to be brave and to be risking your money in a wrong way. Any trader that is using 25x may first be favored but later the person will lose than he will think of. It is not good to do trading like you are gambling. Using a very high leverage of 25x is highly risky.
