The remaining 32.9% who said they knew the concept of cryptocurrencies, were asked another question, in which they were asked, if they would be willing to accept cryptocurrencies as a method of payment? and the result was that 50.4% of respondents he said no .
Their answer is "no" untill people have a demand for paying with crypto
We don't have to wait till when there is a demand for that before using crypto as a payment method.
It's not like there is a general rules preventing it, its just lack of low adoption.
If we see crypto as money, it becomes so.
