I've seen all kinds of bottom trend lines drawn out for the bottom support of the triangle. I am confident about this one. This one lines up with the support/resistance cluster in November last year, and touches perfectly with the Feb and June low points all the way down to the 30 minute chart.
We've been seeing 30 day cycles with trend reversals on the 5th of the month. We saw a teasing of trend reversal on 05/28, 06/06, 06/14, and now 06/28 (not just on BTC but I've seen these dates as possible trend reversal dates on Alts as well). For example I am currently seeing 06/28 as a possible trend reversal date for XVG and GBTC.
If BTC can hold the bottom support line until 06/28 to 07/06, hitting more of a basin phase for a while, I think we could see a trend reversal. The BTC MACD is showing apex in the range of this early July potential trend reversal period. Point D on the chart matches up well with the 08/06 30 day cycle date and the common cluster of support/resistance at 7500 range.
I see this chart as only a possibility. There is of course also the possibility that the trend line busts and it heads down to the 3600 - 4300 USD range. We need to pay close attention, if BTC goes decisively below 6160 in the coming weeks the support will be broken and this triangle with points ABCDE will be invalidated.
