Sands is a Hong Kong option software, which can be used to short and long futures and trade RMB against the US dollar. Their recharge platform is some illegally obtained private accounts, allowing people to charge money into private accounts and convert them into US dollars for trading, which is not protected by law. It is said that there is no need for formalities, but the difference between buying and selling in the transaction process is very large, and the withdrawal needs approval. It takes five hours to approve small funds at the earliest, so it's hard to say if the amount of funds is large. It may be slower or the approval may not pass. I consulted my lawyer and this option app is illegal. In mainland China, it has not been approved by the China Securities Regulatory Commission. The lawyer said that if you have a lot of money, you can be hacked from their app, even if the police can get it back. I hereby appeal to everyone not to be cheated like me. Anyone who is cheated should call the police and shut down their application. Don't let more people be deceived. We should stick together. If you need to know more, you can talk to me in private.
