Hi Killua and starscream,

thanks so much for the reply, both of you. I still don't think people will not buy much with bitcoins when it's is going up in price and I don't think many people will start buying stuff with bitcoins just to make the price go up, apart from those who have been made very rich from it already.   There must be so many people like me with their only intention being to buy at a low price and sell at a good profit
