Like you, I noticed an increasing amount of fairly oblivious people talking about Bitcoin a while ago in our office and that's the most certain marker of an impending crash, but in terms of there being smart money outside of huge investors in the earlier days of Bitcoin I disagree. Developers that like to gamble are not smart investors.
Not exactly true. Bitcoin was extensively used as a money laundering tool to facilitate illegal trade online. The money being used on those bkack-market deals dumped some liquidity into the mix and each money laundering transaction helped back bitcoins with real cash. As bitcoin's adoption as a key part of black market payment systems kept increasing, the increase in demand started driving the price.
The phenomenon was very similar to the one where drug pushers started using Tide detergent as currency, except Tide has real world value and there are no shills pumping its value saying it's the future.
Economists are the worst predictors in this space and the ones that are constantly wrong about Bitcoin being dead.
And then the banks themselves also face countless rules and regulations which result in more hassles to consumers. Happen to keep depositing just below $x for whatever reason? Welcome to a suspicious activity report (for fear you may be trying to dodge financial accounting reporting regulations) and having all deposited funds confiscated until you spend tens of thousands of dollars proving yourself innocent, because in finance innocent until proven guilty apparently doesn't fly. And that's of course just one example among countless.
The current monetary system is pretty much awful. I thought (and think) Bitcoin is the start of a change to this. In other words that it has inherent value. The limits of that value are now being shown as transactional fees get crazy, but the point of this is that I don't view Bitcoin as an arbitrary commodity. It is a decentralized financial service.
...this changed over the summer/fall, of course.
This won't and well.
That's the "pump" part of a pump-and-dump scheme.
There is the possibility that I'm reversing causality here. In other words that the media coverage increased following the increases in bitcoin, rather than the opposite as I'm suggesting. But Google Trends along with the price graph seem to support my suggested causality:

This just seems to be a huge influx of dumb money. If this is true, it's going to lead to some interesting near future volatility. These sort of investors are going to be more inclined to jump ship at what would normally be the tail end of swings. They will see it as 'the crash', race to get out, and create a self fulfilling prophecy. Perhaps offering a great time for investment for anybody who can accurately determine when the double dip decline is bottoming out before a return to normalcy.
