I did that, and then rebought at 130 and sold again at 175, and so on until I only had a couple and then MtGox happened and I lost 80% of that and lost interest for a couple years. It's definitely possible to get in early and not become rich at all.
You should stay away from casinos. Gamblers tend to follow this pattern, they are ahead in between but they always lose it all in the end, they just don't know when to walk away.
Ah yeah, that typical behaviour of gamblers that when they lose it all they stop gambling for years :P
