If you want long-term exposure to a stock but don't want to implicitly make a bet on short-term value, chunk your purchase up into smaller amounts and do it over time (1/10th every day over the next week).

Forget what this is called, but think it's a standard maneuver for wading in to a big long-term position.

If you think there's a 1% chance that a Bitcoin could be a million dollars, then buy 0.01 Bitcoins or something right now. Just do a risk analysis and figure out how much and when you want to invest. I agree it could go down in the short term or long term.
