For a long term holder all these charts and indicators are a waste of time. Current bitcoin market behavior can give you are possible scenario after one or two month it won't be able to predict what will happen after an year. Only historical data gives you an possible accurate scenario of where bitcoin can be after an year. I am not sure about other market but this is quite unique for the bitcoin marketplace.
It can still be an interesting read for long term holders as it is not as if they are disconnected from the market, and taking into account the recent movements of bitcoin they may still be interested in understanding what is going on, however without a doubt this is less useful for them, especially if they implement a DCA strategy, as in that case they do not even look at the price of bitcoin when investing and instead they do so periodically.
