I would invest my bitcoins in studying because with enough money i can buy all the books i want to buy and want to build a career of my own and live a very enoughable and healthy life .
Nice planning, books and knowledge for long term investment.
The only one of wealth that invisible and so precious which you could make much progress to earn in the future.
But, you should consider about another backup plan too in order to get started more early, I mean some investment such as bitcoin is better option.
