Buy and hold, averaging in through the peaks and valleys. That is how you make your money when you're in this early, not quick trades. Bitcoin is a long-term growth play, and a hell of a promising one at that. Any talk of a bubble is nonsense when 99% of the population either hasn't heard of it or thinks it's a joke.
Dollar-cost averaging would probably be a good way to play this market, i.e., invest the same amount of fiat currency on a regular basis. For example, buy $100 worth of Bitcoins each week at whatever the market value is at the time. This way, you limit your exposure when the market is overbought and pick up extra Bitcoins when it is oversold.
This almost sounds like a self-bailout from all the people who just bought in at the latest run up. JK.
