My experience with indicators has not been a pleasant one because these usually lag & are several steps back as compared to using naked charts to read the price action.
And looking at the line chart of the glassnode in the OP this seems like a trending market and a bullish one for that fact...so do I need to read this inversely to get the true picture of the market
Well that is a weakness that all indicators have since they analyze what has happened already, and since most of them are some sort of average in which many past periods are taken into account then this tendency gets even worse as they do not really tell you what is happening at the moment and it is up to the trader to try to determine what could happen next based on their experience and their skill, still I find them useful as they can help you see more clearly a certain aspect of the market and take a more informed decision that way.
'coz long term investors usually disregard seasonal increase nd decrease with the market price. They only view things on a yearly basis. To some it is advantageous wherein they'd be free from stress of minding every downflal on market value but there are also times they're at a disadvantage for not being able to make profit from sudden spikes on the market price. So maybe, it is just a matter of preference. Short term investors would make more (if they know when to buy and sell) in a shorter period of time but they'd be exposed on more risk because they are 'moving' a lot. If we would base on any BTC price chart on a long term perspective, it would seem that its price is continuously and consistently increasing but on a closer look, it is not.
