helping her out like reselling products she needed in exchange for her Bitcoins
I would not call that living solely on bitcoins, nearly none of the merchants accept bitcoins there.
If she gets a crypto backed card with visa membership it would be a lot easier to live a normal life.
In normal circumstances she might not have survived. But her friends helped her out with the necessities. Still I agree with your post. It will be much easier if she gets a Visa or Mastercard debit card, which can be topped up with Bitcoins. I myself owns one.
