Sounds fun until reality hits you with a huge bat in the back of the head.
Bitcoin still isn’t that much popular as a currency of choice. Like @franky1 said, there’s nothing to lose right now if you start a business and accept fiat first. BTC can come later, don’t imagine that if you accept BTC everyone will come serve some food at your place.
As much as I love BTC, I don’t think there’s a lot of potential yet in accepting BTC for your business sales. There’s so much more room for growth and it’s nice having it as an optional payment choice but it won’t bring you that much revenue. Especially in this market.
