I personally see as the network hashrate increases massively, the ease of undermining the network reduces significantly. Thus as the network becomes more secure and inpenetrable to attack, the price gradually rises. I think we're on an steady upward trend now as we have broken away from the psychological $100 and reaffirm a more confident psychological €100 (which is precisely where we are right now). Media will become more poisitive and then hopefully more people realise there is greater profit in innovating the payment process regarding mainstream adoption. Exchanges still remain the weak link and we need a mutual regularatory stance there before the currency can increase liquidity significantly, but these are all positives to come, as well will be private equity pouring in for the currency. All this needs to be approached with care, but i'm not concerned about selling coins personally. Manipulation may occur from time to time, but ceratinly no where near the same as within holding shares in a company, where insider trading is rampant. Obviously this isn't the case everywhere, but corruption is a massive tempetaion as co. managers speak to fund managers, and it's a releif an organic currency such as Bitcoin is free of that temptation to a greater extent.
