kb, while everyone can take a guess - noone on the planet can answer this properly. It is not beyond impossible that the USD keeps falling to cheap toilet paper levels.
If you have a large purchase, I would break it down into smaller parts and buy progressively as it keeps rising. this averages you into a better position rather than risking it all at one rate.
Buy some at parity for example. If it falls below parity buy a little more.
Without a black swan event (war or catastrophe in the Asia region) I doubt it will fall off a cliff as this currency move (globally) is structurally significant.
