1. Too hasty, lack of knowledge
-This is a mistake that most investors when started. The hot growth of the market, the price of Bitcoin growth every day is the main motive for new investors to participate in this market. They are always afraid to miss the opportunity. So they hurried into the market and forgot to learn. So learn first. Be patient waiting for a price you think is good, or at least according to technical and market signals.
2. The goal is too big, greedy
-You should set goals when entering the market just to be profitable. Do not expect too soon to be rich or become a millionaire in a short time. When I join ico, it must reach x $ or x5, x10 for these ico, that actually kills me. When the price fell, I did not sell. That was a big mistake.
Most of the investors, trader has experience, they only want to increase their property by 30% in a month. They are too happy. Remember to a story put the grain on the chessboard with 64 boxes. Patience, not to lose, your property will quickly bulge
Remember to expect 30% of your assets, you are likely to lose 30%, expecting x5 x10 accounts quickly will help you to 1/5, 1/10 of investment capital.
3.Do not stoploss
-This is an extremely important lesson. Any experience or famous investors emphasize this. Stoploss help you have successfully trade up to 80%, do not know how to stoploss, you certainly never win, just fail sooner or later. You can not stop the market trend, stop loss is painless to want to do, but it protects your capital, help you get back to very quickly.
4. Try to resist the trend
-Try to resist the trend
You will be dying right away, which is the answer to trying to resist the crowd trend. In a festival, the whole crowd is joyfully moving forward, you just go back, you are immediately stamped to death. For the market too. When the crowd rushes to buy the excitement, you think the market will fall, you will certainly lose money. In contrast, when the market has strong sell trend, you try to hold the more losses. Get out as soon as possible and go earlier than the crowd.. If you run after the crowd, of course you will be able to die with the crowd, know enough and stop even though the crowd is still running. In every investment, in the long run the crowd has never won. When you are swept away so fast, as the car is so fast, braking slowly no matter what trouble will help you stop safely, waiting for the incident, whether the car is good but you also hurt less a lot of.
I disagree with your # 4 opinion. Going against the crowd really gives a different result. Your example is quite lame and it is not fair.
going against the crowd means going against the crowd's thoughts and actions at a certain time.
I have made mistakes twice in believing in the thoughts of the crowd and believing in the predictions of analysts.
At the time of February of 2018, the BTC price suddenly dropped from $ 9k5 to $ 6k5. Everyone believed that this was the end of the crypto market and there were 4 people in my group who gave up. And I thought the market would soon come back at $ 9k but I didn't dare buy 3 BTC because my best friend said that the market would last for so long. (he has experience in investing in crypto market since 2014)
I was afraid and did not dare to follow my thoughts. and after only 2 days, I was very disappointed when I saw the price of the BTC really increased by 9k $.
The lesson is to follow what you think, but need to analyze it before doing that. Don't try to be different when your knowledge is limited.
