Ever saw a child or teenager trying to act like an adult? Well now try that the other way around. Since you are a smart adult, you might get it done for a day. But for 12 years? You will slip and it will be noticed.

To add insult to injury, after you become grown up, that whole prodigy thing will fall apart, because you weren't actually all that much smarter than everyone else. You were just X years ahead for a child and that bonus melted with the years. So then you wouldnt be a prodigy, you'd be a failed prodigy and that is if the whole ordeal doesn't drive you insane in the meantime and you get hospitalized and drugged up for good.

Finally, even if you manage all of that to then buy bitcoins in the day. "Mommy mommy, please let us put 1.000 € in Internet coins that are 50 cents today. They will become worth 50.000 a piece i know it i promise, Mommy please!". How do you think your mother will react?
