We are not living in a society where cryptocurrency is widely used to pay the bills. If anyone wants to use cash and anyone wants to use cryptocurrency as cashless then both will be considered for me as a customer and I have to give them my service with utmost priority. If the store owner is me, then I must set using both methods to pay. But I can't assure others thinking in this type of perspective.
Yes, this is how every store owners need to think. The customers convenience needs to be provided with utmost priority. At present we don't have high access to use cryptocurrencies on stores and other transactions. But, the small effort taken to accept bitcoin could help with the widespread of bitcoin usage. Particularly people who prefer earning out of cryptocurrency can consider the earnings through stores for holding, because the more we hold more will be the profiting.
