the purpose of bitcoins to make the whole country united by its decentralized system .its main aim is to make the whole world united rather than by its changing its value into their country s currency .it sounds wierd but it happens .and u gotta accept it .
to me ti think the only purpose of bitcoin is to make a decentralize currency of the world. which will be using as a single currency of the world without changing it into any other currency.
but to me i think the only reason is to use bitcoin for online system and facilitate the online traders and those who give preference to online shopping, but as people have still no such awareness about bitcoin therefore they are using it as investment.
