As a long time hodler why do you need to be bothering yourself with watching the market? Your sole purpose is just to keep buying and don't let your attention be bothered by market activities. If your goal is to accumulate and hodl for 6 years and above, then the market timing is not something you should be bothering yourself with. You should just be concerned with getting steady flow of liquidity to inject in bitcoin. Any price you meet bitcoin when you liquidity is available you buy. Let the day traders bother themselves with the market timing.
Bitcoin market is volatile which can create different sentiments at any time among those who follow the market. Those who are committed to long-term holding would definitely do well to keep an eye on how to further diversify their portfolio. Those who understand the value of Bitcoin see the dumping of Bitcoin as an opportunity for them. Those who are short-term investors may be happy with small profits but a Bitcoin holder usually dreams big.
Considering a situation where by a person lacks self control and maybe decides to sell his bitcoin holdings to buy something of luxury when he hasn't built any large portion of bitcoin stash or maybe a newbie investor that started investing with large capital and felt over allocated and just decides to sell his holdings probably because of a little profit on his portfolio to buy a want. So I also think several things could be distractions to us and also hider us from accumulating enough bitcoin as newbies.
It is advisable to adopt a long-term strategy of Bitcoin investment. But holding depending on long-term investments may not be easy for everyone. Some may even convert their bitcoins into fiat before leaving for a specific destination. Keeping a reserve balance is definitely important for those investors. But if they know about the importance of holding bitcoins and if they can do it in the proper way in Dollar cost average (DCA) then they can create a path to solve any problem easily.
