If I had to choose, I'd probably go for the 5.00 CGPA. Education seems like the safer bet for long-term success.
Maybe you will have to ask me again. Education is good but not to be compared to 5 Bitcoin. You need to think well again before you think of the best option. Having a 5 CGPA does not guarantee you any success and you will have to strive after school to look for job so that you can fit in to the society. Investment is what make us rich, and to get knowledge we can always read books so that we can be informed. With such kind of amount, for someone that do not go into school the person will have enough funds to go to school and acquire such degree. You don't have to get 5.00 CGPA as a student.
