I opened an account on an exchange called Bulutun Wealth. When trying to make good profits and withdraw funds, investment manager Ishihara Ippei said, "You can't withdraw unless you pay the tax first." It was reported that the tax rate is 20.315% of the profit. I felt this was strange, and after checking with a lawyer in various ways, it is better to consult with the police in a fraudulent manner. Currently, you cannot withdraw even 1 yen. Please be careful of people named Ishihara Ippei and Nakamura Hiroyuki.
