It is definitely hard at all. It takes literally minutes for you to register, and then just follow the instructions to provide any additional information or document they might request based on your nationality and jurisdiction. The rest also does not take too much of your time.

It's as simple as A, B, C, don't worry. You just register in a couple of minutes and after depositing money you can trade right away.

Maybe to be able to withdraw your profits you'll need to upload some documents into your personal account.

But fear not, it's primarily for the security reasons. To make your account and money less prone to hacking.
