Now a days business and product is for all. Every country exchange their core product with other countries to meet theit demand. What you think Is cryptocurrency help to expand the world business?
Cryptocurrencies are just one of the payment options together with bank cards, webmoney, paypal, etc. Yes, they do facilitate the conduct of local businesses, but I don't think they have a significant influence on the global movement of services and goods.
At the same time, blockchain - the technology which underlies crypto - could be a serious engine of progress in certain spheres like data storage, finance, gaming due its inherent features. In this way, crypto could help emerging new types of businesses and thus contribute to the world's economy.
