That might work if you have a business selling eggs from your backyard chickens or doing handmade crafts in your spare time. Businesses need fiat currency to operate in today’s world, you can’t keep all the Bitcoin you receive. Not because I wouldn’t want that, but because you need to pay suppliers and taxes in fiat. If you’re running a hobby business, you can do it the way you suggest. I’m looking for something else, as I mentioned in my post. We are an "actual Bitcoin business," and our needs go beyond small-scale solutions.
