First of all congratulation to your new development by accepting cryptocurrency in your daily transaction in your shop but sometimes I feel like the price of what you are accepting in bitcoin is not that much I believe the transaction fees may be the the problem there now,well it is a good and mush way to reach out to people who are looking for a way to pay what ever via BTC, people prefer making payments in bitcoin sometimes but we may not really understand some people do not really want to even go close to bank or do anything with bank, so they prefer using the bitcoin as a means of exchange for them
Those who aren't interested in using traditional financial systems such as banks aren't wrong and most of them might also hate it because of their local currencies are getting devalued due to high inflation within the country. Some currencies lose a lot of value and in such a situation, if someone has some money, that money would lose purchasing power which isn't something pleasant in my opinion, and no one would want to experience something like that.
When you have your money in Bitcoin, it is safe from such things. I know that the price of Bitcoin isn't stable and it tends to go up and down, but it at least can regain its value over time, so those who can buy Bitcoin low and keep it, can save us from economic problems they might be facing.
People in countries such as Nigeria can greatly benefit from this.
