I cannot help but to attempt to bust your balls in this regard... and you probably know where I am going in terms of there are some aspects in which you Philip are not a typical kind of OG, because you surely should be in a kind of maintenance stage rather than an accumulation stage, yet at the same time, the kinds of behaviors of selling on the way up and buying on the way down is a maintenance stage kind of activity, which surely any of us could attempt to bias the level to which we might sell on the way up and buy on the way down so that we might be net accumulating or net liquidating... so I suppose levels of aggressiveness or conservative, and so if 90% of our stash is sitting on the sidelines, then that still might be considered maintenance, even if we might consider ourselves as bias in one direction or another and maybe we blow with the wind in regards to where our bias is depending, partly on BTC price momentum.. and in this regard, I may well be defending you, even though that was not my original intent..   .. oh well it is Christmas and almost new years, so why go into some of that.


Actually, you are correct Biodom that there seems to be some kind of glitch in the Matrix in terms of part of the Google spreadsheet that fillippone had posted.   Just for clarification, if you go to the spreadsheet by clicking on the image in the above linked post, then you can copy the spreadsheet into a new document in order to put your data into it.  The top portion of the spreadsheet does not have the formulas in there (so those numbers were based on a different input.  However, if you go to the lower table in that spreadsheet, and you can see that the table has all of the same information, but it also has the proper formulas, so if you change the reinvestment percentage from 80% to 0%, then you will get the proper results in column A, which has the BTC balance at each of the stages after the 20% withdrawals at each of stages in which BTC prices go up, starting at $130k.  Note that once you copy the spreadsheet, you can change any of the portions that have the green florescent cells in order to see the results, and the bottom table seems to have all of the correct formulas.


It sounds like you have the potential tax ramifications figured out, and of course, you might be able to withdraw more than $89k per year depending on how you calculate the cost basis, and I am not going to talk about those kinds of accounting and/or tax matters in any kind of detail  

Surely my price based table does account for your ability to cash out at various prices on the way up, however, you could also decide to follow my other sustainable withdrawal table in which bitmover created a website and a thread in which you could figure out a monthly withdrawal rate and then just figure out if your BTC stash exceeds the sustainable withdrawal amounts, which would be time based rather than price based, but there is a price based component in that one too, since it allows advance month withdrawals for better performing months, or reduced monthly allocations for lower performing months and at the same time figuring out your own level of conservativeness/aggressiveness (in terms percentages), and I have taken the liberty to describe 6-10% withdrawal rates as being moderate under a bitcoin system, and if you don't believe my assumptions, then you could choose a more traditional 4% withdrawal rate... which I classify as conservative and even a growth-inclined rate of withdrawal, when it comes to BTC.
