I feel for that subject matter was it take so might a long time to accept bitcoin.Very first it was not however recognized in some nations around the world.2nd was the charge cost when sending bitcoin.And lastly it will take time to confirm transaction.But it was just i believe/recommendation.
Long ago the bitcoin was just invented the people about the bitcoin were not able to know about the bitcoin because the people were not able to have the internet connection and now they are having this connection so the bitcoin is now very common all around the world and it is famous for all the people. So it is the time the bitcoin is very famous and almost everyone knows bitcoin so they are trying to make bitcoin even legal.
