In order for bitcoin to hit levels of $250,000+...... it will need to be accepted and marketed everywhere. So far, Microsoft accepts bitcoin. This could be the ice breaker and the door opener for other companies such as Apple, Sony, Google, etc down the road, eventually leading to retailers such as Walmart and franchise such as Mcdonalds.
In order for bitcoin to take off to levels that seem ridiculous right now, we will need to see the average Joe not only be holding bitcoin..... but also be spending it. (In this case, $250,000 could possibly be severely underestimated)
Unlike the tech giants and whatnot bitcoin is different. It is decentralized.
Which means that the technology will probably not evolve that much at all. Rather, what has to change is the community itself. All we really need is bitcoin to have more acceptance in society in the form of merchants and whatnot, and the rest will sort itself out.
Stability will come with more merchants accepting btc, which is a plus. I wouldn't be surprised at all if a clear correlation between the amount of merchants around the world accepting btc and the btc price was found in the long run.
