You'll be surprised how much money tweens enjoy spending. For them, it's all disposable income. Another fact is my 10th grade nephew knows more about TOR then I do. I asked him how many students at his school know about and use TOR. His reply--Every one of them. Bitcoin is somewhat of an adjunct of that.

Remember, JB is just an example. Can you think of another known personality this would work for? Maybe some upcoming star?
