First, this is not entirely my idea. Someone posted it in chat, and then deleted it immediately and then I couldn't find them or their chart. But I saw it long enough to get the picture. The 3 bounces prior to this one since $17.8, have all crossed over above 30 on the RSI, on the 4 hour. Generally those aren't oversold enough conditions to make significant impact.
This one is different however, as you can see it crossed below the 30, and that's a bullish signal. Couple that with the double bottom and it makes for a compelling case for a strong rally to the upside. In any case, I'm staying cautious, leaning a bit bullish. Will place some longs if we can get clean above $21,500. But they will be tightly controlled as things are tricky to read right now. There are other indicators working against BTC too of course.
Zoomed in, the chart actually shows a triple bottom forming on the 15m, which is like a double bottom, but more specifically a reversal signal. Regardless of all of this, the chart zoomed out, at a glance, looks quite sketchy, IMO, but I still think we go to low 22k.
