Quantum code is definitely scam. I registered, then got a call, spent almost 3 hrs with a guy on the phone when we were trying to process payment, but thanks to my bank it didn't go through. The guy tried to get my card details to charge my card using another system, I decided to hang up because I was tired. Later I decided to watch the video which was in YouTube ad and it was so dodgy. I started looking and reading about it and it is a real scam, but the only thing I can say, that this scam has been going for few years now. At the moment they keep calling me and today when I asked to not to call me again, the woman on the phone said that they are going to continue calling me, because I registered. I am going to report them to the police.
