About Bitcoin's value: If somebody shows you a gold/silver/bit coin or a $100 bill and offers you to buy it for half its value, would you buy it?
Sure. If somebody offers me a $60 BTC, I'll buy it.
So how about the 100 dollars for $50? How about the gold and silver coins? Lets add a bank transfer: If you give me $50, I will send you $100. I will even send them first if you insist.
What are you trying to prove? Anyone would buy it so that they can sell it 1 second later for instant profit.
