my only advice would have been only invest what you can spare. as you said yourself education is more important so why would you do that.
hope you it will all work out for you. but also hope you have a backup plan if it doesn't
I know some people who invested in bitcoin and they earned and used the money for school fees. Just like my friend he finished his bachelors degree by the help of bitcoin he even pay his own tuition fees and also he can provide his own budget for everyday when he was going to school even his meal. So i salute bitcoin because this is so helpful.
