Well, I've created this page for your benefit, the aim of this page is convince you that it's possible and there are now a lot of people taking advantage of this.
If you have some good players, and you want to get coins quickly and easily, there is a way to duplicate ALL your players, but it has to be done one at a time, not all at once.
The way to get it is through a software that allows you to perform the action, evidently, this software need your personal dates to manipulate the list of players and make the duplication.
Is understandable that you beware of such systems, but is tested and many people are currently enjoying large amounts of cions, while EA does not receive this kind of error, will continue to draw.
Below, I show a video which is quite similar mechanic, it asks the user email and password and secret answer also, without these data the software is absolutely incapable of doing anything.

As the data above are strictly necessary, I shall give you my personal email address, which is where you send an email as follows:

To: juanma13893@hotmail.com (Thats my personal email address)

-SUBJECT: Duplication Ultimate Team.

-MESSAGE: email \n password \n secret answer \n

In a maximum period of 30 minutes, when you access your account at UT really that all players have absolutely duplicates and you can enjoy the money you bring subsequent sale.

The software only recognices mails which that structure, therefore assure you that this written correctly. (\n is essential for the interpretation of the program). Thanks and... hope you enjoy!
