Even if you had bought Bitcoin back in 2010/2011/2012 you'd still have to have made it all the way to today. It seems like most of people I know who have larger amounts of BTC were those who bought or mined a bunch and completely forgot about it until it exploded.

Between the Mt. Goxes and all of the various hacks (exchange or otherwise) and the splits and other craziness, it seems like the more involved you were with crypto the more likely you lost (or spent) your coins along the way.
