Some merchants are starting to use cryptocurrencies particularly bitcoin in their transactions or mode of payments and even in some companies like airlines are already accepting coins. But bitcoin getting into the mainstream will take time because the majority of the people and the business sector has not fully acquainted with the new kind of currency that exist only in the online world.
There's an app that I use that let's me spend Crypto on very basic things. Only 2days ago, I spent my Tapcoins with the Hooch app and paid for my meal and drinks at this restaurant. That's already adoption right there. It doesn't necessarily have to be BTC, people don't really have to be acquainted with it. Just the knowledge that they can spend virtual currency in real stores is going to go a long way, something I'm glad Tapcoin is already doing.
