Opening Post 2: Creating monthly withdrawal limits - based on the then BTC Spot price's direction and distance from the 200-week moving average, and of course a withdrawal rate and quantity of coins in the account
Ideas of sustainable withdrawal that attempts to measure monthly budget limits based BTC spot price relative to the 200-week moving average
There has been a while that I have been talking about a chart/table that I had been working on that attempts to guide monthly budgets within the parameters of the 200-week moving average. Here's an example with two hypothetical accounts.. Account 1 and Account 2.
****An amended and improved version of the above chart eliminates the second Account, and shows the ongoing BTC Spot Price and the 200-week moving Average in order to show how they compare with one another.From the above chart, you should be able to see that if there are two hypothetical accounts, and each of the accounts started out with 21 BTC in September 2022, and they have been experiencing withdrawals on a monthly basis. The amount withdrawn each month should be less than the limits of their monthly withdrawal limits based on the various formulas therein that also peg to the 200-week moving average and also the limits are based on then balance in the account.
We can see that the actual 200-week moving average gets put into the spreadsheet in order to show the limits for the upcoming month. In this case, I have projected the 200-week moving average to be $29,041 (K,3) within the first day or so of December 2023. You can see the actual
here.
The spreadsheet autofills the various threshold BTC spot prices in row 3 in accordance with what percentage the BTC spot price is above or below the then 200-week moving average, as reflected in row 2.
For example, to show the lowest Spot price on the chart (H,3 = $18,850), as long as the BTC price is above $18,850 but less than $20,300 (I, 3) (that is more than 30% below the 200-week moving average, but less than 35% below the 200-week moving average), then there is an authorization to ONLY spend 40% (H, 1 = 0.4) of the 200-week moving average monthly rate which based on the 4% per year, 1% per quarter or 0.33% per month which is also autofill calculated into the sheet (based on the 4% amount in L,3). So the monthly budget limit for that person would be 0.02744205 BTC (H, 20) (or $517.28 in H, 13).
In my model, the BTC spot price has to be 25% (M, 2) higher than the 200-week moving average (which is estimated to be more than $36,250 (M,3) at the beginning of December) before account 1 would be authorized to withdraw the full (M,1) 0.33% per month allocation (as the percentage that is authorized is depicted in row 1), so that would be authorized to spend up to 0.06860513 BTC (M,18 and M,20) for the month and right at around $2,486.94 (M,11 and M,13).
Another clarification that I should make is if the BTC price were to exceed the highest BTC spot price on the furthest left of Row 3 which would be $435, or higher (U,3), at the beginning of December, which is 1,400% higher ((U,2) than then 200-week moving average of $29,041 (K,3), then amount of authorization of BTC to withdraw is still the same (0.06860513 BTC for the month); however there is an authorization to withdraw and to cash out of BTC up to 60 months of the monthly limits in advance..which shows as 4.11630772 BTC (U,20) (U,13 = $1,790,593.86).
Of course once the BTC price gets 0.33% or higher above the 200, week moving average, then gradually the number of months that can be withdrawn in advance increases at various thresholds as reflected in the increases in the percentages above the 200-week moving average in row 3 starting from column N and going through column U. And the number of months authorized to withdraw in advance are reflected in Row 1 and show greater than 1 month in advance starting from Column N at 2 months and Column U at 60 months.
My tentative thoughts is that it would be a preferred practice to cash out several months of the monthly authorization in advance under such conditions of BTC prices many multiples and/or multitudes above the 200-week moving average in order to expect that some of the higher multitudes of being that high above the 200-week moving average are not really sustainable... and we have seen that non-sustainability high spot BTC prices historically, even though we cannot really know in advance how far UP, how fast the BTC spot price might go up and/or how long it will last at various higher price thresholds.
I speculate that as the BTC price is going up and if it reaches higher multiples above the 200-week moving average, we might still get anxious about selling additional BTC (beyond the monthly sales authorization), and so we might still end up selling a number of months of our BTC authorization in advance at lower BTC price thresholds. It seems to me that even if the BTC price were to go 200% above the 200 week moving average as reflected in Column Q, we might end up selling 12 months of our monthly authorization in advance, so it might seem that we could be precluded from selling any BTC for the next 11 months; however, if a few months later, the BTC price were to reach the thresholds in Column S, then it may be quite reasonable to sell an additional 24 months to reach the authorization of being able to sell 36 months in advance (S,1), so we can make those kinds of calculations in order to stay within our limits but not necessarily being overly penalized for selling early even though we would have been able to sell more for higher but we are still able to do it within some reasonable limitations that are still quite generous in terms of the amounts that we are able to sell in advance, and the same is true for getting into the higher BTC spot prices of Column T or Column U.
If the BTC price reaches higher thresholds, there would be new authorization to sell additional months in advance based on the higher BTC spot price movement, and at the same time, we can continue to plug into our formula based on how much we had already sold and based on the 200-week moving average continuing to move up while the BTC spot price is moving up and the higher the BTC spot price is out of line with the 200-week moving average (and for longer that the BTC spot price stays high) then it will cause the 200-week moving average to get drug up faster and faster than it had been previously (and can be measured daily or whatever is ball-parkedly reasonable numbers to use in K,3).. .It can be measured
here, too.
I understand that there is quite a bit of data in the charts and some of the ideas regarding the monthly spending limitations of the accounts are somewhat discretionary, but starting out by sticking with standard 4% per year withdrawal rates and even presume a kind of perpetual ability to withdraw BTC under this kind of system with a kind of underlying assumption that BTC prices (especially the 200-week moving average) will continue to go up at least 4% per year on average, so even if there are some down, years the account is not materially getting depleted in terms of its dollar values (or whatever other utility we might be measuring our cost of living). I also realize that account 1 and account 2 are not very materially different from each other in terms of the current balance of the accounts, so maybe i could have had come up with some differences in which one of the accounts might have hade been maxing out the monthly budget limit and the other one was spending minimal levels.. Maybe a future version I will change them around a bit?
Any thoughts or feedback would be appreciated, or even some real life examples of trying to figure out these kinds of balances. I am focused on BTC in this example, but of course, there could be various other assets that comprise someone's investment portfolio and maybe even cashflow, so surely I am not against any kinds of Gresham Law types of considerations in which there would likely be spending from other assets prior to spending from BTC, so if the accounts are not spent to the max of their limits, then whatever BTC remains would just continue to sit in the accounts with probably a need to consider whether to maximize withdrawal or to sometimes even hold back on withdrawal or to maximize withdrawal which is also partially already guided by the parameters and assumptions contained in the chart/table.

a website to help to figure out these calculations and also a
new thread by Bitmover.
