Those who have been cheated by unscrupulous cryptocurrency traders or had their credit cards frozen, please read this...

Let's first look at the operating principle of the first-hand black currency dealer:
Part-time workers (college students) are tricked into registering exchange currency accounts. The registrants do not know what they have registered for, and then they place orders to buy U and connect with the telecommunications fraud market.
When retail investors pay U to unscrupulous cryptocurrency dealers, the dealers will call them and tell them that their bank cards have reached their limit and they will use their family members’ cards to transfer the money to them, saying that the funds are frozen safely and compensation will be provided.
Retail investors have no experience and think it is a big deal. They agree and provide their payment cards. The currency dealer then sends the retail investor’s bank account to the market staff. The telecommunications fraud personnel at the market will send the retail investor’s card number to the telecommunications fraud victims, and the victims will transfer the money to the retail investors.
