It may be just me, but I have an even lower percentage withdrawal rate, somewhere between 1-2% a year.
We can back test various withdrawal rates, and see that historically, BTC has been been appreciating in value more than 10% per year, even using the 200-WMA, so historically we would have had been able to get away with 10% withdrawal rates and the dollar value of our holdings would have continued to grow.
Surely 4-6% is even more than reasonable with bitcoin's historical performance, and surely would likely amount in considerable ongoing growth in the value of the BTC holdings, in spite ongoing withdrawals, and a 1-2% withdrawal rate would even be allowing the value of the BTC holdings to go up quite a bit, especially if we might average out the withdrawal numbers over a whole cycle or more. Withdrawing at ONLY 1-2% would pretty much allow for fairly aggressive growth in the value of bitcoin holdings, which may or may not be a desired outcome, even though surely I am aware of people ongoingly being worried about their retirements stashes holding value, which seems to be more of a problem in fiatlandia rather than bitcoinlandia, yet still returns are not guaranteed yet we can take precautions to lessen our withdrawals during periods that the BTC price is less than 25% higher than the 200-WMA (if we so choose - which may be prudent).
For sure as the BTC gets withdrawn, the authorized amounts would get smaller in terms of BTC amounts, in the event that we held the withdrawal rate the same in terms of percentages, such as withdrawing at 4% to 6% per year. Of course, the greater the cushion in a persons budget size, the more likely he should be able to feel comfortable employing higher withdrawal rates in terms of percentages, again as long as he would be valuating the sufficiency of the size of his BTC holdings based on the 200-WMA rather than based on BTC spot prices.
I had previously used the backtesting tool, described as Simulation on the website to show that fairly high rates of withdrawal would have historically been sustainable... such as 6% to 10% and even higher, and I believe that I even used higher rates than 10% to max out the tool, even though the tool maxes out at 30% per year.. and you can even experiment with 30% per year and see that your BTC holdings hold up pretty well, especially if you might have reached a status of adequate (or over) accumulation even as far back as 2015 or earlier. Do you think that I should go through those scenarios again and try to show how it plays out with the tool? which I prefer to spread over at least a whole cycle (meaning 4 years) in order to really get a sense for how sustainable withdrawal could work (or be calculated in terms of reaching an adequate BTC stash size).
Maybe you want to give me some ideas of what you would like to see or otherwise I would come up with my own scenarios, if you want me to show how to use the tool in terms of backtesting some kind of a withdrawal that spans at least over a whole cycle... so for illustrative purposes, the latest date that we could start would be 4 years earlier than today, which would be late 2020...yet we could go back further, too.

I understand why you mention 30 years, since frequently in traditional financial circles, investment advisors will describe 30 years as a kind of target timeline for withdrawal of funds, even though to me it seems that any kind of withdrawal rate should be sustainable in a perpetual way, and not necessarily limited to 30 years, so therefore, there should be no need to have to be OLD in order to start to employ sustainable withdrawal as long as you conclude that you are ready to begin based on your stash size, whether than is 10 BTC or some other amount that you might have had achieved (talking in terms of hypotheticals rather than the holdings of any particular forum member).
And so frequently we are going to want to employ a withdrawal rate that averages less than the rate that our holdings grow in value. So surely, I am not contemplating any system that unnecessarily depletes the principle of our BTC holdings, and for sure, I would rather than guys error on the side of conservatism in their withdrawal until they are sufficiently comfortable that it is going to sufficiently hold value in terms of their assessment of its valuation, yet it seems that anything at or below a 4% withdrawal rate would be quite conservative, and perhaps NotATether's suggestion of a 1-2% is overly conservative, and his suggestion of such a low withdrawal rate may well mean that he figures that he has not quite reached a status of overaccumulation of BTC to justify employing sustainable withdrawal including that he still wants to continue to build his BTC holdings, and 1% - 2% annually may well be so conservative that it may well work against his best interest, unless for some reason he is still wanting to grow his bitcoin rather than withdrawing from his BTC in a meaningful way in which he can know that he has already reached an over accumulation status.
Again, I have no intention to talk about the actual BTC stash sizes of any particular forum member in term of figuring out what might be considered overaccumulation or the employment of a budget that I believe would provide of sustainable withdrawal, whether we are talking about 1 or 2 BTC or 10 BTC, or 20 BTC or some higher quantity of BTC as our speculative budget.
This part is likely true, especially if guys are valuating their holdings based on the 200-WMA rather than valuating on BTC spot prices, which can be quite erratic, as many of us have surely witnessed over the years.
By the way, I have looked at the forum registration of each of you guys (@Poker Player and @NotATether) and surely each of you have been through a whole bitcoin cycle, yet it still can be difficult to presume that merely 4-5 years of BTC accumulation would put a person at a point of overaccumulation of bitcoin, so I can see that, contrary to my earlier suggestion, neither of you would have had gotten to over accumulation by 2019 or 2020 unless you either greatly front-loaded your BTC investment or you had begun investing into bitcoin several years earlier than your forum registration dates.. and sure.. yeah of course anything is possible, and so maybe we could look at scenarios of BTC accumulation between 2018 and 2022 and then start our withdrawal strategy in 2022, yet that would still ONLY be 2 years of withdrawal, yet surely I am open to proposals in regards to hypotheticals that either (or each) of you might want to attempt to visit (and/or bat around in terms of sustainable BTC withdrawal ideas).
