This is an interesting prospect and one I wouldn't oppose. I don't travel much, but it would be a form of exchange, a form of payment that is less than a hotel cost and not centralised either. It would be beneficial to all. I think it would be cool for there to be actual BnBs where people pay with crypto, any crypto currency they choose, Steem, BTC, LTC, etc, and there could be a few around the world. Employees would get paid in crypto and people staying there pay in crypto.
