This channel tracks back to the start of 2013. I'm not saying it's foolproof, but it has been somewhat reliable as a possible range for which bitcoin operates in. We have yet to get a touch of the 2.618 fib in this cycle. Whether that be due to diminishing volatility as the price appreciates and as time progresses... or if we simply have not concluded the entirety of our bull run. The reasoning for the ladder to be the case would be the growing intelligence of the marketplace for Crypto, and specifically Bitcoin. This, in my theory, would inherently force whales and larger interested entities to suppress price, in an attempt to attain their preferred chunk of the pie -- while also deter retail from sustaining a majority interest. All of this is simply a hypothesis of mine and in no way should be interpreted as financial advice. Hope you like it!
