This will force bitcoin to become better. The top currency will have to earn its spot. Just because bitcoin was first, does not make it the best. Facebook was not the first social networking site by a long shot. Nor was the mining pool deepbit the first mining pool. I foresee many new blockchains starting up but only few of them will be at the top.
Bitcoin has had a good start, but at this point in time, it needs some serious organization to make the currency we all have hoped and dreamed for it to become.
We need PR, marketing, simplification, and more liquidity. And most of all, we need products and services which make good use of bitcoin, something like silkroad... just more legal.. when it comes to silkroad, bitcoin fulfilled an actual need. We have yet to see an effective micro payment system, I want to see something that works in a SINGLE click.
