Every time I panic, I give my brothers confidence in scientific evidence. How many brothers got off the bus due to panic in this wave, and how many brothers listened to advice and decided to invest or buy at the bottom? Many brothers in the fixed investment community have gradually changed their investment thinking, and many brothers have begun to move towards profitability. In the cryptocurrency circle, cognition is above everything else (holiday essay): 1. Make money that you can understand, don't touch coins that don't understand blockchain logic, no matter how good they are. 2. Good hunters must be good at waiting. The cryptocurrency market operates 24 hours a day, and they must also wait for opportunities with certainty. 3. The most important skill to learn in cryptocurrency trading is waiting. Wait for the foam to recede and consensus to gather. 4. Always be wary of the market, as every "insertion" of the candlestick can be a trap and an opportunity. 5. Capital first, protecting capital is the most important. Surviving in the cryptocurrency market is the key to a bull market. 6. Survival in the cryptocurrency industry is a lifelong skill that tests one's character more than simply learning skills. 7. Carefully study (project), patiently observe (quantity), rest assured (trend), and successfully sell (profit). 8. Never fill the position, there is no upper limit to the volatility of the cryptocurrency market, and sufficient positions should be reserved to cope with extreme market conditions. If you dare not buy and hold the time traveling bull bear, don't make a decision to buy. 10. Take advantage of the situation and never expect to succeed in buying at the bottom. It is possible for the coin price to return to zero. 11. There must be a safety margin and stay away from air coins without landing scenarios. There are not many currencies worth investing in, and 70% of the top 100 will still be zero. Don't enter easily. Discipline is important everywhere, especially when it comes to controlling high leverage. 14. Consensus is overwhelming, and the rise and fall of coin prices are essentially the aggregation and dispersion of market consensus. Before investing, first understand yourself and clarify the bottom line of fluctuations and losses that you can tolerate. The key to winning in the cryptocurrency industry lies in staying away from FOMO emotions and lively contract casinos. Learning makes progress, but if you don't understand wallet security and smart contracts, you will eventually stumble. Most of the time, it's not a misunderstanding, but a lack of patience to wait for consensus to erupt. Patience is the watershed for retail investors, only those who can withstand fluctuations deserve to double their returns. 20. Value investing, slow is fast, chasing gains and killing losses is not as good as cultivating mainstream currencies. 21. Great compound interest must be accompanied by strict profit taking in the cryptocurrency industry in order to be secure. 22. What is the basis for judging the track and currency? Is it a white paper or market sentiment? 23. Understand every question you don't understand, especially the token economy model of the project. 24. Idle money investment, consensus investment, stay away from leverage, and stay away from low-priced air coins. 25. Investment is for making money, and in the process of making money, one learns to understand consensus and risk. 26. Three thousand weak waters, taking only one ladle to drink, the mainstream currency is sufficient to carry reasonable returns. 27. Only by giving up can one gain, and only by being willing to succumb to the temptation of high leverage can one keep their principal. There are no experts in the cryptocurrency market, only winners who survive and losers who go bankrupt. 29. Think independently and don't be misled by the tricks of "all the good news" and the manipulation of market makers. 30. To understand why you can compete with others and become the one who makes money: do you understand risk control or have patience?
