Zero.

Bozo's got his head up his ass. He can't even do simple arithmetic. Says he made 500 BTC on the spike down into the lows, but if that were to be true, he'd have to have been responsible for around HALF of ALL THE VOLUME on that move, or something like 1200 BTC, i.e. over a million and a quarter USD. Does anyone think MasterSchmuck was responsible for half the DASH market with over $1,300,000.00 during those 20 minutes into the lows? Especially after bragging about selling at the lows (that unwittingly idiotic statement that sounded good to him/her at the time)?

Zero. If anything he's lost money again.

Bozo's a zero.

He/she has the psychological profile of the pathological liar, not so much malicious to begin with - it begins quite innocently with the survival technique of responding to the unknown with the idea that, "okay, if it sounds good, then it must be true", and then the person relaxes in his/her own little reality bubble - but that can sometimes turn into something not so benign and even lead to psychotic and schizoid behaviors that can be detrimental not just to the individual in question but also to third parties.

As long as you humor him/her with good nature, keeping in mind that the only value his/her statements have are what they reflect about his/her internal hallucinations, he/she can't do you any harm. Think of him/her as that mentally challenged youngster with their head somewhere we can only imagine - if you treat them with loving care, never taking seriously anything they say (except when it's "I have to go to the bathroom"), there's never any harm done, and, what's more, they give you back thousands of times the amount of love that you give them.

MasterSchmuck needs our loving concern. Tell him/her yes to what he/she says. Tell him/her how wonderful his/her last trade was and how great it is for crypto to have someone like him/her to be making such a valuable contribution towards its future.

But always be clear, it's always a figment of his/her imagination, that being said, it often sounds very good, very real indeed, because even though the problem is that it's all made up, I didn't say anything negative about their creativity! It often sounds so good, that normal people buy into the idea! But the pathological liar blows it when they go overboard with things like making 500 BTC on a 20 minute move into a spike bottom where the theoretical maximum that could have been made (all the volume sold at the top of the move just after the break, and all the volume bought at the absolute bottom - which we know is just as impossible as accounting for all the fluctuations in between, but let's exaggerate and give him/her the benefit of the doubt) is just a little over double that. Sorry, but that just didn't happen. More likely he lost 0.5 BTC on the move.

TLDR: Don't pay any attention to what he says, and the best option is to humor him with kindness (much better than making fun of him as I suggested before - you'll get much better results treating him as an "amusing sidekick"), otherwise he'll get you so messed up that you'll make very bad decisions and do yourself a lot of harm, no doubt about it.

Another reason why critical thinking is so important. Like I said before, it's your job to police/self-regulate your coin . . .
