Managing finances and only investing the amount which we can afford to loose has been taught since ages but how many have followed this to be honest? Quite a few, and those few are not top traders amongst their circles.
If only people know how easy and simple is to follow this rule in trading, it will save alot of people that loss money to trading. The market has been bullish this year, even though some alts are not making good moves but I can say that I have acquired some good profit. There are some days that I do make loss but overall, my trading strategy has been good too me, I don't over trade and I don't use more than I can afford with a tight stop loss.
Yes, every trader should take a step that excess is not good but it is not right to expect more than your own ability. Since you profit according to your ability with experience and using stop loss, this is definitely a great process for you. The market was quite bullish this season but some altcoin markets were not very good due to which they went towards bad positions. However, if you can trade with good experience and skill then you will not lose but you will profit so you should always analyze the positive and negative aspects.
