Ongoing publicity about Bitcoin on financial news sites and magazines will be attracting the interest of serious investors. There are thousands of individuals and institutions for whom 10 or 20 million dollars is a small amount to devote speculatively. Especially, in this case to prevent themselves being blind-sided by arguably the most significant applications-level development to the internet since the world-wide-web itself.
An inflection point is approaching, signified by real-world metrics such as the exponential rise in usage of the blockchain.info wallet service.

In Bitcoin terms, this would mean an investor trying to accumulate between 200k and 1 million BTC based upon the maximum issuance figure of 21 million.
Needless to say, only the first and possibly second investor which tries to gain such a holding has any chance of succeeding. The whole ask wall would have to be vaporized repeatedly to achieve it.
The long-term small investor should be wary of selling too many bitcoins (when trying to re-buy on dips) because the mother of all green candles could occur at any time, ramping the price, say from $20 to $40 where it would find a new level to continue from.
