We invest into bitcoin or any other investment with an expectation that we are going to be profitable, even though we know that we are not guaranteed to be profitable. We also have to know that the short term is very hard to predict, and even bad things can end up happening in which our investment is no longer strong, whether we made mistakes or whether something related to the asset ends up having problems to weaken it as an investment.
Naturally, no one puts money in an investment planning to not make profit, making profit is the primary reason for investment and while there are no guarantees for profit, there are strategies we put in place to increase our chances of profit, its also prudent to know that short term investments are at a higher risk of not making profit and as such short term investments should be avoiding, if the plan is to make profit in bitcoin, then long term investment is the way to go.
If a person is coming to bitcoin with an expectation to be staying into it for 4-10 years or longer, then by looking at the extent of BTC's volatility (and unpredictability of price direction), there should be little to no expectation that the investor's capital will be profitable in the first several years, and they should actually not be considering profits to be very important in the first few years of investing into bitcoin, especially since they likely are still in their BTC portfolio building phases, so there could be some advantage of not being in profits in the beginning, which means that they BTC price had likely been gravitating downwardly through their ongoing bitcoin buys.
I generally talk about 4-10 year or more investment timelines in bitcoin because I would not want to dissuade anyone who at least has a minimum of 4 years that they still are going to be able to invest into bitcoin, yet based on the way that bitcoin has historically been performing within the context of cycles, I would consider that 4 years would be the minimum timeline to be able to reasonably consider bitcoin as an investment rather than as a trade.
So personally I would consider 4-10 years as a short term investment into bitcoin, and surely since I also frequently talk about sustainable withdrawal, I consider that guys should not be building their bitcoin investment in order to cash all of it out, yet it would be better to employ some kind of a sustainable withdrawal that can be price-based and/or time-based (and I have
a thread talking about sustainable withdrawal ideas).
But, yeah of course, anyone can do whatever they want when it comes to how to treat their bitcoin once they reach their goals and if they have inclinations to spend all of it or to invest in other assets, even though I consider there to be a lot of value in the employment of sustainable withdrawal practices, guys surely might have their own reasons to follow some other way of managing their bitcoin holdings and/or if they believe it is a good idea to completely sell off their accumulated bitcoin after perhaps spending many years building up their bitcoin stash (and hopefully the value has appreciated during that time too)..
By the way, regarding long term DCA with bitcoin, I believe that we can have a presumption that bitcoin's price trajectory is going to be up for the long term, yet even if we have a presumption, we are not guaranteed that bitcoin's price trajectory is going to end up playing out upwardly.
A reasonable assertion, treating 4-10 years of bitcoin investment as short isn't a bad idea, though its definitely long term for some other investments, but relatively short for bitcoin due to it's volatility and unpredictability, and I can't say it's very smart to immediately sell all of a person's bitcoin assets once they have met their investment time, sustainable withdrawal makes sense and while it can be time based or price based I believe it can also be percentage based, maybe sell like 10% of your assest when a person wants to sell. But ultimately, it up to the investor to decide whether to sell everything or to employ the use of sustainable withdrawal.
