First of all, funds should flow overseas. In this international transaction, capital goes abroad, not in RMB, but in foreign currency. Therefore, when investors identify the authenticity, it depends on whether the funds are in RMB or foreign currency. Second, the question of who to give the funds to. If you invest overseas, the money will flow into overseas gold investment companies or market maker platforms. So it won't be a domestic company that receives your funds. If you receive your funds, whether it is RMB or US dollars is problematic. For example, if an American wants to do A-share market in China, he must open an account in China and trade stocks. On the other hand, if China people invest in gold abroad, they should also export it and turn it into a recognized currency abroad. Third, about investing in software. When investors use it, or simulate it, they will find out whether the price will suddenly slip. When there are no signs in the market, the price suddenly fluctuates so much that it can't land at all for a certain period of time. Some of them may be caused by the busy system. However, as real international standard market makers and gold companies, their systems have experienced many storms, and people from all corners of the country have to trade through their platforms. Their technical strength and support are very strong, and basically there will be no login failure. The software will only be discovered after everyone uses it, including whether there is any abnormal state in it, and everyone can access it during the use. The company's capital flows overseas, and the software is downloaded from foreign standard official website. At this time, there was a problem.
