Honestly speaking, I am never confident in charting BTC but this is my first attempt to establish a trend with BTC using only Support & Resistance and Fibonacci Retracement tool. Also, please forgive my explanation as I find it hard describing what I see. :)
Twice now, BTC has followed the 0.618 retracement pull back.
#1 Rally - USD 1,000 to USD 3,000 Pullback - USD 3,000 to USD 1,800 (0.618) News - ICOs Boom
#2 Rally - USD 1,800 to USD 5,000 Pullback - USD 5,000 to USD 3,000 (0.618) News - Hard Fork & China FUD
Then BTC changed trend and retraced back to only 0.5
#3 Rally - USD 3,000 to USD 7,500 Pullback - USD 7,500 to USD 5,500 (0.5) News - BTCG and SegwitX2 Forks (or suspended fork)
Now there are two possible outcomes that I am predicting will happen with BTC (bullish prediction of course): Using USD 7,500 as support since it is previous resistance.
I am going with #4.b as BTC followed the 0.618 trend twice which has a better chance of happening. (Note: Using only data spanning from May till today)
