The only challenge I face right now is 99% of our customers are female, and most do not have any prior knowledge of bitcoin or cryptocurrency, the ones who do either heard about bitcoin from their partner or social media campaigns but they havent given it much thought. Its popular among the male folk here, I am yet to have a customer pay in bitcoin but its good enough to start the conversation.
With time, they will come around it and may likely embrace the option more than fiat. The concept behind the workings of Bitcoin is one enough to fascinate anyone. However, my worry in all these payment with Bitcoin thing is how likely are those who aren't Bitcoin hodlers going to continue to get Bitcoin for the sole purposes of making just payment without using it for basic trading and other stuff. I say this because of the volatility of Bitcoin and how $50 could easily become $20 within hours.
