The adoption of bitcoin acceptance by the Magento community and merchants will largely be determined by the growth of bitcoin as a whole.
I don't think anyone in the magento community would be apposed to adding bitcoin as a payment option to their site, as long as its actually needed.
Furthermore, the ease of use will be a huge factor. With the likes of apple pay and other payment methods making it very easy to checkout with ease and speed, the same would go for paying in bitcoin. If its cumbersome to pay in bitcoin (find wallet address, copy paste, figure out the exact decimal to send, transaction fees ect) No one will want to use it.
Once customers want to regularly pay in bitcoin rather than some other form of payment on a regular basis/scale, I don't see whole ton of value in implementing it for a store.
What sort of data do you guys have? How much volume of online purchases through eCommerce stores are currently being paid in BTC?
