This is really awesome. We are really experiencing the potential of Bitcoin use. As of now it is very difficult to survive with Bitcoin for entire life style like from hospitality to food etc., But she did a great job and she is able to survive 21 days with 0.21 BTC.
The girl seems to be attractive on her own, even without any bitcoins (and makeup), but with a nice look and pretty face you can survive for much longer with no money in your pocket at all. I think that when she asked to pay for food and shelter with crypto, the managers were willing to treat her with lavish hospitality for free. She likely just needed a little bit of practice at first with her approaches and attitude to get everything she wanted
To conclude, this doesn't look like a test of Bitcoin potential
