If you accept Bitcoin, you are faced with the decision to price in Bitcoin or your local fiat (or some other fiat). If you price in Bitcoin, the potential mid-term upside is huge, but the short-term downside can wipe you out and your customers will be angry at what they view as inflated prices. Also, your prices will be highly volatile against the currency that your customers hold.

You also need to have a wide profit margin to even benefit from Bitcoin transactions because your suppliers probably won't take it, so you have to cover the conversion cost. And then there's the task risk and compliance costs.

Yeah, really not easy. Probably lose money with it.
