This is exactly what I have said more than once: in order to attract buyers to pay for goods and services in the real sector in bitcoin, it is necessary to attract them with discounts.
Although no transactions have been made yet, many customers ask me about the posters and how to pay with Bitcoin.
Make a discount a little more and
BTC-transactions will definitely appear, because for those who don't yet have bitcoin, will need to buy this (minus the exchange commission). Therefore, the 5% discount should be after deducting all conversion and transaction costs on the btc-network.
Even taking into account the discounts provided, you will still make a profit (because you get an asset that is growing in price, and don't store money affected by inflation), and besides, you attract other people to use bitcoin (and advertise), which is already worthy of praise.
Btw.
You'd better replace the poster (it looks artisanal and low quality).
It is better to frame it, choose the appropriate font size and color (yellow is a bad choice).
