The monthly chart does not show a lot of useful stuff. We see price seem to get to an “hard” cap at the monthly level set at Round Number 83,000 ISK.
Like many other items and commodities, it looks like there’s a slight uptrend in prices across the years.
The whole market is centered around Big Round Numbers (BRNs) 60,000 – 65,000. That is, there’s a two years fight that pulls price below and above those values, this tells us that 60,000 – 65,000 is the current long term “fair” price. This also suggests to find buying opportunities when price is below that amount and to sell above, possibly near the monthly level. However, knowing price wants to go to 83,000 it’s never a given truth. Price may decide to stop early. Because it can.
