I do not accept the bitcoin in my business because the fact is that no one is really interested in it from my customer so that is why I do not accept it right now.
how do you know that your customers are not interested in paying you with bitcoin? did you ask them about this and they said no?
maybe you should add the bitcoin payment option (bitcoin is accepted here sign) and then see how many will use it. it is not that hard to do it you know.
Yes people will ask you only if they see that bitcoin is accepted at your place and unless you don't display it no one will come to know about as they must be thinking that you are not aware about bitcoins.
