Does technical analysis by others hold any weight for you when you're trading?
Yeah. I follow dozens of other traders, partly for fresh ideas that challenge my biases, and partly to measure trader sentiment. When most traders are all leaning one direction (either bullish or bearish) it usually means they are piled on the wrong side of the market. Short vs. long and open interest data can contribute to this sentiment analysis too.
In my view, technical analysis isn't much more than looking at charts and drawing lines. So called analysis that focus on bitcoin markets tend to completely overlook factors such as volumes even.
There are no perfect methods to price analysis, whether fundamental or technical. TA when properly used should give you an edge against the market. It doesn't equate to printing money.
Volume is a crucial part of my TA. High volume usually signals exhaustion at S/R and price extremes. It also tends to confirm dominant price direction in newly established trends.
The half-trolling "wall observer" thread in bitcoin talk seems to me like a better observer of bitcoin prices other than any of the well know technical analysts that focus on charts. This whole "science of charts" seems to have very negligible predictive ability if we're going to consider the ones that are public at least.
The WO thread is another useful source of sentiment data. It's no surprise they were mostly bearish a week ago.
I've seen many BTC analysts come and go over the years. Skilled technicians who offer consistently valuable insight are few and far between, but they are out there.
