#btc Bitcoin fluctuates widely, and copycats are flying everywhere. This prediction seemed to be OK a few days ago. The key is that despite this, many people still cannot make money. Why? Here is an empirical indicator. If you do short-term contracts, then set your own profit-taking target and play with the popular currencies of the day. If you are not good at short-term, then block the rising news of other currencies and only buy for yourself. Otherwise, not only will you not make money, you will also lose money! ! !
