Jack Dorsey, the CEO of Twitter and Square, expects bitcoin to become the single global currency within the next decade, he told the Sunday Times newspaper.
Square said in November that it would start enabling the buying and selling of bitcoin on its Cash app. Dorsey is also an investor in a star-up called Lightning Labs, which is developing technology to make bitcoin faster and easier to use.
When it first came into use, Bitcoin was touted as an alternative to the dollar and even gold.
Dorsey told the Times that bitcoin is "slow and it's costly, but as more and more people have it, those things go away."
