Ok I've been running some thoughts and numbers in my head about CEX. Right now it is .04189 a GH so 1 Bitcoin would get you about 23 GH's. I have about $14,000 in a couple stocks right now that I am thinking about cashing out and buying bitcoins at the current price of $850 I could get about 16 Bitcoins. Now if I bout GH's with those 16 bitcoins I would have 368 Gh's (not including my BFL 60), at the next predicted difficulty level of 1,549,680,471 I would earn .1194 BTC per day according to bitcoinx.com. So if I did this for 30 days I would earn 3.582 bitcoins but with difficulty increase probably 3 bitcoins in a month.  Then I sell my Gh's hopefully for what I paid for them or more I could make a profit here I think, and then put my money back into stocks. My goal is to just get about 5 bitcoins total and then store them on a flash drive and CD for the next 10 years and then come back and look at them.

Any thoughts if this could work?
Thanks.
