I don't know where you live, but for sure you can try to accept Bitcoin in your business. Maybe after a month, you should came back and give an update about your business, compare the profit between people who pay you with Bitcoin and fiat, so we will know does everyone are prefer to use Bitcoin or fiat to pay in real life. Because not all people want to reveal themselves if they're Bitcoin enthusiasts.
I think trying to accept Bitcoin in business is not as easy as we imagine,
almost everyone seems to still use fiat as a means of payment,
for now people use Bitcoin only as an investment or trade.
It is true that for now accepting Bitcoin in business is not easy.
Actually OP put forward some great opinions and suggestions and I think that's visionary thinking.
And I think what the OP said might happen massively in the future but it can't fully happen now.
There is still a lot to consider regarding where we live, the regulations and several other important factors.
The thing that I think needs to be remembered for now is not all businesses can run by accepting Bitcoin.
There are businesses that require cash turnover and quick returns on the spot to return business capital.
In fact, at this time we will still need fiat money to keep our business running.
I hope OP and the people who have accepted Bitcoin as a means of exchange or payment in their business have thought about it carefully.
Not just joining in because they are tempted by the benefits that Bitcoin provides without thinking about the risks.
