Bitcoin have 0 infuence on world economy because bitcoin is still young value which many pupils even dont use.In my country 1/500 pupils use bitcoin even less I dont know real informations I am just guessing.
What is pupils, I believe you are using a mobile to post that's why you have no spell checker right? note that bitcoin should never have any influence when talking about the big pictures here, what matters bitcoin has a significant effect on individuals and their lives and has the potential to do impact in a positive way on millions though not with current block size.
