You know how volatile Bitcoin is and many businesses do not want to deal with the volatility tide but a small set of them do accept and convert to stable currency asap.
Crypto or stablecoins they all can go with as payment gateway. Lot of companies in some countries are already accepting them all.
There are businesses that accept Bitcoin as payment, but only supermarkets, even big dealers that deal multi million dollar deals do use Bitcoin as means of payment.
If they don’t become versatile to accept several means of payment, it means they are not ready for business because some people can have Bitcoin and will want to use it direct to purchase goods online or somewhere, they don’t need to pass through the stress of converting the Bitcoin into stable coins before the buy they purchase car or anything, and it is good and will increase Bitcoin adoption globally.
It is now let for the business person to swap or convert the Bitcoin into stable coin due to crypto market volatility, and they can as well start their investment journey from there.
Only big companies can be willing to accept bitcoin presently as it will be very difficult for some small scale business men accepting payments in Bitcoin cause dew to it volatility it is quite difficult to make account for when dealing with taxation obligations.
Not accepting Bitcoin in a business does not really make the business person not serious with business specially for those geographies where Bitcoin is not given a positive recognition by the authority and it really not that taken to be a legal tender either.
