It shows your customers that you are a forward thinking company. Bit of a loaded assumption that; accepting bitcoin has nothing to do with being forward thinking. Bitcoin appeals to human greed, that's it. The comments comparing this to Linux and TCP/IP is apples and oranges. Why would I as a hard working member of my society with a house and kids invest money into a system completely unregulated. I'm all ears.
at a base level its regulation is completely transparent and algorithmic, unlike the closed-door regime of central banking.
Edit: don't get me wrong, I have crypto currency I've blown many a kw/h on. But you can not as a society rely on a currency with such flaws. Hell maybe insurance startups will popup to handle the issue but I'm not holding my breath.
