Well since you bring up valid points. I will let you know then that I came upon this gift card as I do online surveys through several reputable survey panels. Most paying PayPal and some paying Bitcoin. And for completing a survey about cigarettes. Which was rather lengthy compared to most. I was awarded the usual $3 Bitcoin and also an added bonus of a 10 Amazon gift card. Also yes my account is rather new. But an old one I had was mysteriously hacked and I am no longer able to access to my dismay. Also I have made a similar trade recently with a well respected member of the community for $25 which I graciously sent to him and patiently waited several hours so he could have it put to another card.
Your concerns are reasonable and hopefully my truthfulness in my response are enough to quell any fears you or others might have.
Plus it's only $10 so if I give first and get scammed so be it. But i know it will not be the other way around.
