It is really important to think about our potential losses, most people are always thinking about the profits that they can get, not understanding that whatever potential profits they imagine they could get are unattainable if they lose all their capital before they get to that point, with that in mind it is really important to concentrate yourself on not losing all your money in a case you hit a streak of several losing trades but that can be a really hard advice to follow when most people never imagine that they can lose at all.
Thats why alway set stop loss and manage your risk because the market are crazy it can be pump or dump anytime, margin trading is risky if you compare to regular exchange site but like other said high risk is equal to high profit. Dont be fooled and control your emotion anytime dont be greedy if you think you have a profit then grab it.
That is a sensible advice but very few people want to follow it, besides they do not have a systematic way to set stop losses, how can they decide when the market has gone in the opposite direction of their prediction too much to the point they have to sell? That is a difficult question to answer and one that traders have to face all the time when they are trading, and this is something difficult to figure out in the moment when we consider the huge psychological pressure you are felling at that time.
