I also saw a few coffee shops in Europe paying for crypto. Hoping that other areas will accept payment, trading with crypto will increase the market.
These few coffee shops is enough to spread the spirit to other shops overtime, because I am sure that those receiving cryptocurrency for paying will start having more customers than those who are yet to adopt it, and as they say, curiosity kills the cat, as they become curious to know why they are making more sales, they will find out about cryptocurrency and probably adopt it too.
Aside these ones, we also have many companies that are already engaging the services of developer on how to integrate cryptocurrency payment into their business, especially those who are making use of online stores to sell and promote their products.
