If you are heavy in bitcoin, and especially if this is your first bubble, I would ask you to consider if you still feel good if the price goes to $0.3 or $0.4. Otherwise it might be a time to sell a fraction of the holdings now at the record prices.

For those new in bitcoin, this is a very good time to enter with experimental/speculative funds, and buy more when the price goes down.

I do not suggest daytrading bitcoin to anyone: like all speculative markets, it is heavily manipulated, you pay fees, waste valuable time playing a zero-sum game and generally end up on the losing side of the trade. Optimally you only accumulate bitcoin until you have enough (never sell), and once you have enough, you gradually start to sell/buy things with it (and never buy back coins). This minimizes the problems outlined above.
