well that's pretty impressive but why are you mentioning Indians and why you want to know the share of Indians? Maybe because they are taking too much interest in Bitcoins well if so then they may have a great share in the market. We can only know if the exchanges tell us how much bitcoins they are holding or we hear anything from them otherwise we cannot say anything. But right now i guess people from all the world are taking interest in Bitcoins.
It could be because we are from India, and Indian economy is growing at the good pace compared to other countries in economy and when compared to bitcoin we are far behind then other countries. With majority of population being young ideally we should be leading in bitcoin technology but this is not the case yet. Let us see how far and how much we can go ahead.
