The next boom will occur when all of the companies we know and love start accepting Bitcoin. It has already started happening. Overstock was the first. 711 in all of Mexico was a large boulder. Dish Network was a surprise. And NewEgg seems to have jostled loose several precariously positioned internet based rocks that don't seem like they can hold their position for much longer. The mountain is trembling, soon they will all start falling, and then it will become a full blown avalanche.
I predicted at the beginning of 2014 that Bitcoin will touch the 5 digit mark before 2015. I may have been wrong about that, it's still tough to say, but what is sure is that the next leap forward will occur with the corporations and merchants every where accepting bitcoin. Not that people will be spending Bitcoin when this happens, it's still too early for that. But the option will become available across the board, and the groundwork will be laid for that future dream of full blown world wide universal bitcoin adoption.
I think maybe after the corps have started accepting bitcoin, the step after that will be the fall of the fiat moneys all around the world. But of course, all of this is pure speculation, and I might be insane.
