Look at the volume pushed through the market... did you noticed how overpriced the trasactions were?
Have you ever heard that some wealthy billionare threw some national bank to its knees by just pushing some huge amount of money through forex exchange? Was he sentenced to jail? No...
Food for thought:
a) If you have one bitcoin, that is 1/21mln part of all bitcoin capital that will ever exist on the market... If you consider global wealth and try to estimate it just for US, it will be something around M3 definition. M3 is M2+something more than M2 i assume. If M2 is 10,2 trillion USD and M1 is 1,2 trillion, So M3 (total USD) would be (10,2/1,2)*10,2=86,7T$ (http://money.howstuffworks.com/how-much-money-is-in-the-world.htm)
b) If you assume that other countries have 10 times more wealth in total, compared to USA wealth (take saudi arabia for example, they sure have a lot of money, maybe as much as half of USA) you can make a conclusion that total world wealth translated to $ i 860,7T$.
c) If George Soros was able to throw down bank of England because of his one billion of dollars (that is 1/860700 of global wealth) are you able to throw down the bank of england by trading on bitcoin volume that would be equvalent of 1 billion dollars?
d) How much you would have to trade to throw down all the banks?
