We can't conclude or judge easily because Industries and Technologies had been rivaling since the beginning like for example:
1. Macintosh and Microsoft
2. Yahoo, Google, Bing etc.
3. Nokia, Blackberry, iPhone, Samsung etc.
etc...

These mega companies were once an idea, then developed and gain huge profits while others were merging trying to innovate and compete against other rival companies.
And so as Virtual Currencies, let's see and wait how they grow or drop or maintain the effectiveness and shares in the market.
