If you had a Coinbase account, you could've bought up to 50 in the last week or two around $300, and now could sell them all back and make about $10,000.
It's not at all hard to buy and sell now as opposed to back in 2012. There are tons of options. Of course where the price will go is anyone's guess..
Edit: I should add that I did my transactions on bitstamp. Used to use MtGox earlier but it's not worth it, too many issues with them.
