It is all about discipline, it is all about determination and it is all about your goal. Some people's Bitcoin purchase goal is to keep it for decades, this is cool, just pray that you do not have any financial issues, that should be enough to be the fuel/willpower needed to take your eyes off it. I also advise Bitcoin investors to keep their eyes off the chart, they can make mistakes with that, so checking it once a month or quarterly is okay. If you trust Bitcoin, why not buy and leave it like those who leave their stocks for years, if not decades?
A long term bitcoin investor make plans for emergency funds in case they run into any financial situation that could have led them to selling their bitcoins to attend to that situation but since they already have funds they have kept for any emergency need, it will no longer be a problem to them. A long term investor has no business with monitoring charts, all what they are concerned about is making accumulations at different intervals, that is for someone who is still accumulating using the DCA strategy. They already know the target they have for their investment which will make them become more disciplined to wait until their investment ripe before they can take profits from it. Those who have strong love for bitcoin can hold as many years to want to hold it without selling.
For those Bitcoin accumulators who are looking for a sure source of emergency funds and discretionary income but don't consider setting their DCA timeframe, it's a sure way to build a future without any unnecessary noise. Here's an opportunity to add BTC units for those who are deposit regularly and potentially bearish period rather than needing to monitor charts. You should keep yourself focused on long-term goals to qualify for potential gains including occasional aggressive Bitcoin buying to weight the portfolio.
You should clarify your statement about maturity in Bitcoin investing as you said. What I mean by maturity is the goal of accumulation Bitcoin until retirement because you will continue to earn while you are working and a sure source of Bitcoin accumulate will remain active in that situation.
