This is just what I have encountered. Several other users came forward to speak out against it. While they may have credited you with that I would highly advise making sure you can withdrawl it. If they are legit, good for them, and I wish you the best of luck, However I would be cautious as these are classic signs of a pyramid scheme.
Be careful
Be safe
