In 2017, a big shot told me: if you're doing a project, just do a public chain. The ceiling depends entirely on imagination. Later, the public chain he led was completely abandoned. This statement is correct - most projects in the cryptocurrency industry are not profitable and rely solely on imagination to support their market value. How big the foam is, how good it is to tell stories. In recent years, there have been countless pitfalls, and a few valuation criteria can be summarized: 1. Can it be profitable? It doesn't matter if the market value of profitable projects is larger. What cannot be profitable is all air. 2. Look at the absolute value of the total market value. Total quantity multiplied by price. When the project team wants to smash the market, there are a hundred ways to sell the coins. 3. Check the concentration of chips. Spending some time on Etherscan can reveal the tricks, the more concentrated the chips, the easier it is to manipulate. Most economic models are nonsense. For so many years, only BNB has conscientiously carried out the destruction. other? People who have experienced HT destruction all have headaches. 5. Oversold major exchange currencies are worth paying attention to. The Binance currency with a total market value of 10 million dollars, with a shell that is also valuable, may be bought by large funds to tell ghost stories. 6. Do not conduct technical evaluations. Having good skills can easily lead to faith losses, while having poor skills can easily result in being deceived. 7. Hot weather is deadly. If the chips are scattered, no one has the motivation to make market value, and the combined force of 10000 people is zero. 8. Community activity level? Fake or wool washed products have no reference value.
