At present, most of the coins sold on the market are junk coins, not the bottom. Those who say that the copycat coins are all at the bottom are either bad or stupid. Shouting the slogan of the bottom means you are going to buy the bottom. When you think it is junk, you will not buy the bottom. When the time really comes, as long as you are willing to spend money, instead of predicting that the bottom is a long way off, you can't bear it in your heart, and eventually you will stop loss and leave. So, why not go with the flow and don't waste it when the financial sentiment is good?
