What the heck is that??

Dear Trader,

Due to security reasons in order to protect your funds, we had to temporary restrict the functionality.

1. Please set the 2 factor authentication.

2. After you do that, please fill the form and provide the necessary documents.

After you pass the procedure, all the functionality will be restored and your account will be upgraded to the tier with the lowest fees for one month.

Our only goal is to keep your funds safe. Thank you for your understanding and cooperation.
