At a very young age, he's thinking is already in advance. Not all 12 years old can think that way. Some people will choose the money instead of Bitcoin because they see it as no value. But the student thinks of it as an investment and I am amazed.
I think He invested his bitcoin initially into the business, then bought back by selling the business from what I read. He is not an average high school. What is the probability that a 12 year old will invest in bitcoin by then? It is not possible for experienced parents, let alone small children. It must be a genius + luck to stumble on bitcoin at the right time.
I read this a few days ago on reddit. We all want to be this person and retire early, even he is the type of man who keeps going after getting rich.
