I hate to break it to you all, but unfortunately, rampant speculation, the hack attacks and massive price drops have already essentially killed bitcoin from the credibility point of view. No large company will willingly use a currency if using it risks their profitability on the scale bitcoin does.
Such a volatile market also has the potential for ENORMOUS gains. People have made quite tidy sums of USD from BTC. THat wont go unnoticed by investors if it continues. Rewards require risk.
When you want to accept payment in btc you don't want it to arbitarily drop in value and make you essentially sell at a loss. The only thing the volatile market encourages is
more speculating, rather than actual marketplaces.
I wont disagree with that. But if the speculation drives up prices, more people pay attention to bitcoin, then more people are likely to try it, use, it, and create an economy out of it. Win/win/win.
