I want to open a cafe where you can spend bitcoins
Remember that it is not online source is risky, in every investments all of them are risky like the cafe that you are planning to do so. And that's a very good idea that you will have to accept bitcoins so that bitcoin users can simply go to your cafe and pay you with their bitcoins. For sure other cafe's near you will adopt it when they figured out that you have the payment method.
The competition will be tough but if you are the only cafe that has that feature of method for accepting bitcoin. Maybe you can attract more crypto customers and those other customers that are curious with bitcoin will have a time to know how it can make them save a lot of time and effort for adopting this currency.
What country are you from and why do you think there will be lots of crypto customers for his cafe to make it have the advantage against his competition in the cafe business? Im not here to judge you, so out with it, what country are you from?
Im guessing youre from India or Bangladesh. Are there enough BTC users there to justify starting a cafe that accepts BTC?
I think that even in such a country like US or Great Britain something like that would not change a lot, it just seems like a stupid idea to start a shop/company that rely on bitcoin, unless you want to make it an online service or something.
Paying with bitcoin on streets is still rare, the fees and confirmations make micropayments less attractive, for example I dont even use something like that.
Yeah, sometimes I cant find a reason why they keep saying that a normal, offline shop would benefit a lot by accepting cryptocurrencies. Then the moment you ask them why they cant answer you and start ignoring you.
