Try to find other ways to pay for your school, you can use your bitcoin for that of course but you are going to regret every single bitcoin you spend and that you do not hold, believe me I know while I never had a big amount of bitcoin the small amount I had was spent in useless stuff and if I had hold it I would have bigger profits than the ones I have now.
