We need first to introduce the Bitcoin as currency and their value, because how the local businesses encouraging if they cannot know the value of this currency? Moreover, we need a lot of advertisement regarding the usage and benefits they provided to the users/businesses.
So how can anyone know not the value of bitcoin, when it is just that easy to type "bitcoin" in google to see how much it is worth?
I have to agree with the fact that someone may have never heard about cryptocurrencies, or bitcoins but the value case is fairly easy to solve, it is just going into google.
Without big amount of transactions sent daily through blockchain, and a really big number of people participating in the cryptocurrency world, we won't be able to encourage merchants to using bitcoin as a way to pay for the products, because it won't be simply worth for them. Not enough customers would use bitcoin payments, to consider implementing such a solution into the shop/store, unless it is shop with digital goods.
