First of all, I want you to understand that you are not doing anything wrong, and that everything you said or experienced is normal, not very many people own bitcoin or other form of crypto currently, this is to tell you how new this technology still is to many people, they might have heard about it but are yet to fully get themselves involved in it.
And again, it also depend on how big your business is and how much and the kind of customers that patronize you, all I can say for now is, continue to offer both crypto and fiat payments to your customers and put your focus on growing your business and your customer base,  the time will come when you will start processing more bitcoin/crypto payments than fiat.

And also note that over 90 percent of those who currently own crypto actually see it as an investment, and not a means for paying for goods and services.
