So far, I have not seen a chart similar to this posted on Tradingview, perhaps people knew of this and I am just one of them to stumble upon this, however, I think this is important.
What I found:
There was a strong total RSI trendline that occurred around September 2014, and until 2018 the market has been supported by that trendline. Only until January of 2018 did the total fall out of that RSI trendline in addition to falling out of a trendline that appears to have been made in early 2017.
In November of 2018-April 2019, the total hit a trendline that was made in 2015-2016, during that period, accumulation occurred. It is highly likely that BTC and the entire crypto community has bottomed given this truth.
