But first, I think what investors are really looking for in a cryptocurrency is its stability, having a less volatile value as possible. Because you really canot afford to lose much money especially during massive swings and reversals-- it is just very risky. Stability and Security is what it would take for bitcoin to attract more people.
Maybe there is a very small percentage of investors with such a mentality. From my understanding these investors were the one who make the market highly volatile for large scale profiting. Volatility is the major attraction of the cryptocurrency network, maybe there is chances of loss but investors weren't that careless to invest and leave as it is without keeping track of the market moves.
