When BTC dumped from 64.8k to 47.6k in, it tested the neckline of its head and shoulders. When creating a fib extension downward, the 1.0 extension was found at 29k exactly. When BTC dumped from 69k to 42k, it tested the neckline of its head and shoulders. When creating a fib extension downward, the 1.0 extension is created at 17.2k precisely. This is just an observation but I find that it reinforces my dump to 17k thesis.
