When speculating in cryptocurrencies, you should speculate in leading stocks, only leading stocks, and not miscellaneous stocks, because when the price rises, the leading stocks rise the most violently, and when the price falls, the stocks are the most resistant to falling. Don't be afraid to get on board. Speculating in cryptocurrencies is often against human nature. Don't buy because the price falls a lot, and don't stop buying because the price rises a lot. The more you dare not buy, the more it rises, and the more you dare to buy, the more it falls. The strong will always be strong. The most important thing for short-term speculation in leading stocks is to buy at high prices and sell at higher prices!
