Why do we lose more money when we shout about the bull market every day? The previous track was simple, there were few currencies, and the market value was low: In the early days, there were limited projects in the cryptocurrency circle, few choices, and the market value was low. At that time, as long as you chose a good project and held it for a long time, you would have the opportunity to make a profit. Now there are many tracks, many currencies, and high market value: Nowadays, the cryptocurrency circle has more tracks and currencies, but the market value has also become higher, and the market competition is fierce. If you still use the "hold" strategy, it may not be suitable for the current market environment and may even lead to losses.
