For 10.000 to happen, there are basically two ways:
1. Bitcoin is really adopted as a currency by many people and businesses all over the world, for example dominating the remittance market. That would mean that we would need better usability, and also probably less volatility. So this way would be the long one - not less than, let's say, 5 years (I expect 10). In this case, early adopters will really have the chance to be a "wealthy elite". But it's the hard way. Some people here in this subforum, I think, would prefer ...
Mass adoption does not equal price rise. Sure, people may buy and hold it so the speculation then is what makes the price rise anyways. However, when people start getting into it more as a currency and use it, then they will buy and instantly use it for goods which then the person who had the goods uses it (or most likely sells it at the early stages because fiat is still strong). So excluding the mining fees it's a net neutral transaction, not a net profit.
