bitcoin is simply amazing. bitcoin can be used in various stores as you mentioned. people are starting to see bitcoin as a good investment. so widely used for sale and purchase transactions. bitcoin also provides convenience in transactions so that the transaction is done peer to peer. this allows all ornsg to use bitcoin as a future transaction. maybe in the future bitcoin becomes an alternative payment. not just clothing stores .. restaurants, hotels also receive bitcoin as a means of payment. this is amazing.
I do not think like that there are many sites who are accepting bitcoin but there is no huge number of users to access it. You need to have a better marketing strategy to make bitcoin famous to all level of people.
Not only for clothing, bitcoin should get accepted in any business, projects and services how important given for paypal.
