Bitcoin vs. Alternatives

Hello, I've recently began to get into buy and selling Bitcoins and other cryptocurrencies, because of this I don't exactly have a lot of cryptocurrency (currently 0.0001BTC Yeah!). However, while trying to earn as much as I can while I wait for my financial information to clear online exchanges I began to wonder what would make a cryptocurrency become the defacto cryptocurrency, and one thing which bothered me through the process of setting up my accounts and getting Bitcoins came to mind. Speed (with some convenience and safety of course). I figure whoever comes out with the fastest cryptocurrency will more than likely become the defacto cryptocurrency. Am I right in thinking this way or is this wrong to assume. If so why?

(Please keep in mind that I have a limited understanding of the technology of cryptocurrency it is new to me).

If you'd like to help me off to a great start in the Bitcoin game
