It's no news that cryptocurrency has come to stay, but the industry is still unregulated and that is a major problem that inhibits growth. Amazon can integrate Bitcoin but due to the unregulated nature of the cryptocurrency ecosystem it may wait for sometime to see regulations before it fully integrates BTC. The problem is not BTC the problem is thr market and whales.
That's the problem I see too. They would love to integrate it, but they cannot because of compliance issues. They've probably got some pretty stringent conditions in regards to how they are supposed to handle money and payments. How are they going to collect the payments? When do they cash out to fiat? Sure, it sounds easy, but when bureaucracy becomes involved, these issues get convoluted. They just want to make sure that everything is "legal" so the big bad tax man doesn't come knocking at their door.
