or wait and see if the market crashes slightly?
The market crashed slightly many times but unless it doesn't go back to $8,500 you should buy already.
if you are talking about the recent drops (multiple of them) in the past 20 days, well those weren't exactly crashes, those were corrections that needed to happen because of the fast rise from $6000 to $9000 and they in fact keep the market healthy and they assure the rise continues upward as market takes a break and refuels for the continuation of the rally.
a crash is what happened from $10k to $6k and $6k was the price that everyone should have bought at because it was the bottom.
