I've been watching the BTC price for what seems like forever.  Coinbase charges 1% in fees.  I figure if I can (for example) buy at $225 and sell at $228, then I've made over 1%.  It doesn't sound very hard.  I will have my coins instantly if I register my credit card on Coinbase, right?

EDIT: Plus then I get to spend more time reading the hilarity scrolling up the BTC-e trollbox.
