Are those 5 waves composing an A in a larger ABC structure? That would be a bit of a stretch, would mean BTC is literally going to zero :O.
I assume you are meaning an ABCDE correction; I'm not much into ABCDE triangles, but I don't see clear 3 waves in the B (2) and D (4).
Anyways, use this as a rule guide and reference: http://www.cabafx.com/trading-ebooks-collection/Corrective%20wave.pdf
