Please teach me how to fundraise... I'm lost

My dad just recently bought a stake in his first alt coin and he was super stoked about it. Only to find out a week or so later that he has stage 4 colon cancer that's already spead to his liver, kidneys, and glands.
He is uninsured because of high obamacare premiums. and now uninsurable because of his advanced condirion.
I wanna do something to help him with his expensies but I don't have the first clue whereto begin. I've never even borrowed money from anyone let alone asked strangers to give it freely. Any help would be truly appreiciated. Thank you
