Yep! There are loads of people now who are using Bitcoin and accpeting bitcoin on their stores but ofcourse there will always be a risk on it as the price is volatile, it can go pump and dump at the same time...If you arent sure about it, then why not just go with USDT?
It's true that many people now are using bitcoin but there's more people who doesn't know about bitcoin itself, since it just began to be in the news where its because of the big impact that elon musk invested the profit of tesla into bitcoin , maybe it was a good decision to use bitcoin for payment for those who really are into bitcoin and ofcourse there are big risk into it for being volatile and no one can blame that if the price goes down or up because it was your decision at first to accept bitcoin in his store.Also it can be an eye opener for those people who really doesn't know about it being curious about what bitcoin is and start using / searching for it and become a investors too.
