Bitcoin ASIC price trends

I'm trying to spot signs of miner capitulation. Came across this Bitcoin ASIC price index chart on TheBlock. Not really a miner myself, so I'm a bit lost on how to interpret this thing. Anyone got tips on reading it? Also, is there any link between this chart and miner capitulation? I can't help but notice all three lines are heading south.

The three lined represent three different efficiencies of miners. More efficient miners are more expensive because they use less power (so are cheaper to run). You'd generally not replace old hardware if it's profitible until you have to or use the components of old hardware to replace the components of new hardware (in cases where there's compatibilities and it doesn't involve the actual mining chips - such as the fan or the case). It's hard to compare them with the other charts as they only have 2 years of data for the other charts. From my experience, miners go up in price around the halving (when price goes up and there's a reason for it, and they'll normally keep going up until they can't anymore - such as miners not expecting to be paid back and impulse buyers disappearing). I've seen mining firms release a new miner, put a big price on it and drop the price if they don't all sell within the time they expected.

According to my research, this was I discovered try to find out by yourself. The blue line is Under 38 joules/TH (38 J/TH) The red line is 38-to-68 J/TH And the Green Line is  Over 68 J/TH Hope this will answer your question anyway, Good day Referrence: https://data.hashrateindex.com/chart/asic-price-index
