Mats problem is that he is stuck on the idea that the only right way to make money is to daytrade. Realizing that he sucks at it, he doubles down and loses even harder.
Meanwhile I just made a hundred bucks in two minutes by buying on localbitcoins and immediately reselling on kraken. There are plenty of ways to make things work for the open minded.
I think that you are correct. There is a kind of mindset that wants to keep doubling down and leveraging, and even when those kinds of folks might have periods of rationality and logic, they let a kind of greed - or gambling or rolling the dice - take over their actions.. and periodically they win really big, but in the long run, the odds catch up with them and they are constantly attempting to dig themselves out of holes.
So we should continuously attempt to caution folks against this kind of approach, because it is dangerous - and even if they have won BIG TIME in the past, they gotta consider better long term approaches that may not make as much money but help to set themselves up for longer term profits and/or financial security.
From time to time, I have some of those kinds of Local bitcoin (or direct) trades that cause me to experience an immediate $100 or more locked profit, and sometimes it can take quite a while to put sufficient systems in place (having money in a multitude of places and floating the money) to be able to lock in those levels of instant profits, and really, the practice of profits may begin with much lower levels of profits and just getting used to locking them in on a regular basis. I frequently have trades that only have $1 or so profits, but sometimes, they will run a streak and I get locked in profits from a multitude of small profits, but having the smaller profit locking in system in place allows for the taking advantage situations and opportunities for larger profit trades, without putting a large portion of the principle at risk.
