The customer service of Prospero Markets says that it needs to pay 20% tax in order to withdraw. Because of there are too many requests of withdrawal, you need to deposit 18000USD to upgrade to premium member and process withdrawal from express channel. Then, they also said that the green channel can be opened and arrived in 24 hours with a deposit of 17500USD. But, it has been five days, the customer service staff said that the financial department is arranging the withdrawal for you, and it has not arrived for a long time. I am very worried.
