Yes, possible. We all know that bitcoin is a well-known of all coins in currencies. Majority use bitcoin in different kind of ways like paying bills money transfer etc. They use bit coin in many porpuses. Many people choose bitcoin because of its ability to give satisfactory specially when you are investing.

it is hard to predict if bitcoin becomes the world's first currency and we will not know how the future of bitcoin will be. the public is more confident banknotes made in the country's banks than bitcoin, because paper money has become a means of payment since antiquity before the existence of bitcoin. paper money is also how to get it and use it is easy.
I do not think that Bitcoin is designed to be a world currency Bitcoin does have great potential and is quite interesting. It's a matter of time before most countries will turn to crypto currency as their national currency. It needs a lot of improvement before we can use it in our daily lives

No doubt that it will be. it was made for this purpose.

it will be decided future will give a proper answer to digital currency,when the digital currency head of bitcoin will become the first world currency for buy and sell transactions. 

It depends on government.We need to wait for future.

Well ... Perhaps in many, many years it will be possible but definitely not in the near future. Many are not ready for this especially not who are not familiar with the crypto currency

Exactly i am agree with you and it is true.

I do not think it can do that. We can not deny the benefits it brings to the world, but its instability does not make it possible to become the world's currency. In addition, overdue supply will not be eligible. It is impossible to become the world's currency for Bitcoin.

I think it's the most expensive buy and sell to all exchangers and all the exchanger I knew bitcoin was the first one I saw here and this was the leader because many people also invested in it and it was the ruler of all the coins.
