@cryptovestor, When I was trading my own FX account for a living, I would not have done so without the Fibonacci Retracements tool. Many FX pairs were prone to deep retracements:- 61.8% was a regular bounce level and even 78.6%. I don’t think Bitcoin will behave very differently. I’m looking at a completed pattern from this time last year to Bitcoin’s high. If the market gives back 78.6% of those gains, then a large number of crypto participants will be in for a shock.
