The biggest concern right now about bitcoin is the unregulated nature of the coin which can be manipulated easily and also the possibility of bitcoin usage to finance terrorism and illegal activities. Not to forget the amount of energy required to mine bitcoin is alarming, up to date bitcoin mining consume more energy than 159 countries in the world. Considering all the facts, i dont think bitcoin move that far and people might change better and update version of bitcoin such as DASH, XRP or LTC which has significant advantage over bitcoin.
