Three types of people who lose money in cryptocurrency
1. Playing contracts manually
2. People who play all-in and touch the Ponzi scheme, and the project owners run away
3. People who play short-term will lose money even in a bull market. They dare not buy when the price drops, and do not want to sell when the price rises. They chase the rise and sell the fall.
In the cryptocurrency circle, those who hold the big cake for a long time do not lose money.
