The problem with me is that I start feeling guilty thinking that my gain was somebody else's painful loss.
Unless you scammed someone then you should not feel sorry or guilty about your profits, if you are going to use that kind of thinking then you should feel guilty about every single dollar that you get, after all if you work hard at your job and your boss pays you then he is losing money in order to pay you and yet you do not feel guilty about being paid for your job don't you? This is the same, if you do a good job in the markets then you are going to get paid but if you don't then you are the one that needs to pay the market.
Funny, I was thinking about this today. What I feel guilty, I guess you can say sorry for people who are new to this, don't know much and innocently lose their money. Or people who had no idea of crypto being told by a friend or family member to invest in this, they trusted them and then lose it all. Like I feel really bad for such people, and the regret that they must feel.
You should not feel sorry for such people. There is nothing you can do in this situation. There are a lot of people who would follow the instinct with just few details and that is what derives a lot of new investors to invest in bitcoins just because they were been suggested to invest. In this situation, they would never consider the current price and would enter the markets at any price they feel convenient.
Majority of such traders end up buying at the peak and that is what makes them bear the loss. Any kind of investment should be treated a lot cautiously as there is no way in this entire globe where you could simply earn benefits just for the capital you invest. You also have to use your brain in such investments.
