I'm sure the number one thing bit coin is used for is trading but that wasn't its original use and seeing how it still has value and exists a decade later it has utility. Officially what else is it used for? How could you find this out there isnt a wall street journal for bitcoin. But there must be a prospectus for it out there or as close to one as possible. Is there a way to read the original white paper?
BTC is a digital currency that uses peer-to-peer technology in making transactions such as payments. Well, it was like a cashless system wherein payments are done digitally without 3rd party during the transactions. The reason why most people think when we talk about BTC is trading since most people are involved here and articles related to BTC always talk about its market price and movement. So it's only natural to feel that way but BTC was originally created for a digital payment system. Don't forget that.
