The square is full of people who want to cut your leeks. Small investors, you should know that big investors and bankers look down on your little money. Those who really want to cut you are either playing around by themselves, or those who want you to pay membership fees to join the group, especially those who teach you to play contracts! Of course, how to identify them is very simple, just look at the name, such as: xx currency, encryption xx, Bitcoin xxx, xx Finance and so on! A very simple logic, if they are big money guys and can predict the trend, they would have been financially free long ago, why would they still need to worry about your membership fee? They are all pretending! Open your eyes, in the currency circle, either you cut him or he cuts you! Go with the flow, spot is king!
