I'm thinking he must be a troll. No way anyone can be that reckless.
Definitely losing 75% of your capital by trading an asset that went from $13 to $900 in less than one year sounds fishy. You really need to be a special kind of retard to do that.
It's entirely possible, I assure you. I personally know someone who has enormous difficulties resisting emotional impulses even in normal daily life. If she ever got into trading or gambling greed and panic would ruin her in no time.
