The break below 6k was extremely significant because we consolidated on it for so long and everybody thought it was the unbreakable bottom. So, when we broke it, it was inevitable that price would fall through many supports before finding a turnaround on the strongest of supports, which many thought would be 3k (because of its previous strength & if not 3k then where?).
Calling this exact bottom would have been difficult because it didn't reach 3k, however these are the factors pointing to 3215 (3115 on coinbase/mex) as our new bottom:
1) Descending wedge on descending volume (textbook turnaround pattern) (red)
2) The craziest RSI & MACD bullish divergence this chart has ever seen (green)
3) Buy volume breakout after we pushed past 3380 up to 4k
We stopped our recent run at the 4H 200 MA/EMA and are coming back down on descending volume (suggesting the formation of a continuation pattern).
$3650 is the next strong support - a previous bottom - which coincides with a nice trend line to put buys on and watch for a breakdown, however, anywhere between 3800 - 3650 is a strong buy on this chart.
