We really encountered that one, but let's just pass it. Still, I was shocked about saying Bitcoin is a scam, because at that time, I would say here in our country, only the old ones really know Bitcoin. Usually, almost all of them heard about it and know what it is because it was already discussed on television. I think they really have a lack of awareness and knowledge of it. Just keep your payment method open in case someone wants to pay you for fun.
To be fully honest, accepting Bitcoin in my store is mostly an experiment. I didn't implemented BTC payments with the goal of profiting from it.
