First, funds. If you don't have enough funds, you can't become a professional stockholder. If the money is too small, even if you earn it every time, you won't earn too much, more than 50W.

Second, technology. No skill is nonsense, and no amount of money is thrown into the water. Of these two foundations, technology is relatively more important, of course, both are very important. Because even if your money is very small, for example, only tens of thousands, then you are super skilled, and every time you limit the price, you need thousands of dollars every day. The problem is that you don't have this technology.

So you should carefully consider whether you can really be a professional stockholder.
