Are there any success stories of people who have done this? How easy is it to buy/sell? I heard something like "a mass sale would trash the price" so why hasn't that already occurred?
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.
