It's hard to tell the time frame...but ask yourself if you expect BTC to catch itself now and start climbing steadily the way it used to ? Hardly. You can almost feel the fear, and if you were an institutional investor, you would smell the blood and want to wait for a lower rate.
If you were a retail one, you would... well I guess you would ask yourself, as you just said, when to take advantage.

I can only advise to watch whenever you can and be conservative with stop or buy orders because they may be triggered by deliberate hunting action while you sleep.
I personally expect 7600 to appear soon but there's others talking 6000 and looking at the next support levels close to 4k.
That is bad because it's unnecessary but if the mood is bad enough it will happen.
Market makers will be testing the possibilities.
The only valid counterargument is that there wouldn't be many sellers remaining soon, and that the true hodlers cannot be made to sell by mere FUD or an artificially crass drop.

Or can they ?
