This is a very interesting topic for discussion. I think that small merchants at the initial stage can attract customers to themselves by the fact that, unlike other stores, they can pay in cryptocurrency. As is well known, additional concessions to the client often play a positive role in trading. In addition, the audience of cryptocurrency holders is constantly growing. First, it can be in the form of an experiment, and then as one of the methods of payment. If this experience becomes successful with small sellers, then at first other small sellers will begin to enter payment for cryptocurrencies, so as not to yield to competitors, then medium, and then large ones.
It will not only benefit the small shops but it will also give confident to the crypto community as when they will see their coins being used by the merchants then they will start to take more interest in their coins and will stay with their coins to support more.
