0.03 BTC sounds very high even for a 10 BTC budget.
It may be just me, but I have an even lower percentage withdrawal rate, somewhere between 1-2% a year.
The rule is originally intended for people who are retiring, so that the money could last about 30 years. If you haven't reached at least 60 maybe that's why it seems high to you.
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, 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, 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, and for sure, I would rather than guys error on the side of conservatism, yet is seems that anything at or below 4% would be quite conservative, and perhaps NotATether's suggestion of 1-2% is overly conservative, and it 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.
Although I personally don't think the same. Bitcoin will continue to grow above inflation, well above it for many years, so with 4% or less you will not only not run out of money, you will continue to gain purchasing power.
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).
