That is one of the purpose of cryptocurrency - to help businesses grow incredibly. Cryptocurrency offer advantages which harness the payment systems of a business and in the end promotes work productivity. Crypto offer good payment speed, low transaction fees, security etc for businesses which adopts it into their payment systems.
The cryptocurrency might not help the mankind to fight with the economic problems but it will definitely help to expand the global business. The crypto will help to make the financial operation between the countries faster and safer.
I beg to differ a bit about the statement that cryptocurrency is used almost all over the world. It is not use in the south Asia which is home to one fifth of the entire world's population. The absence of the technology is the region is a turn away from the globalization of the system however; there are other ways to expand the business to the rest of the world as well.
Anyhow, the role of cryptocurrency in spreading the business activities around the world cannot be ignored because the only factor that can boost your economy is the speed and the scale of the business activities in the economy and cryptocurrency seem to play a big role in this regard.
