May be we can dark the colour of 200-Week MA line on main graph and bold it, so it looks more prominent.

It will also be good idea if there is zoom in and zoom out functionality in Graphs. Like Graphs are showing data from 2013 to 2023. If you can provide functionality that can allow us to see data for say last 5 years or 1 year only.

Presumptively if we are withdrawing in a conservative way such as below 6%, then the dollar value of our BTC would have good chances of going up, even though our BTC stack size would be going down, and presumptively if we are withdrawing between 6% to 10% then the fiat value of our stash may well stay at similar levels, and finally the more aggressive that we are beyond 10% then the larger the chance that we are depleting our stash value in terms of its ability to sustain its dollar value at the rate we are withdrawing it... and we label 17% and higher be extremely aggressive and the tool allows going up to 30% per year.. but yeah visualizing how that might affect our level of sustainability might take some higher level math skills (referring to my own challenges to come up with what the right formulas might be and then how to display that .. .which also kinds of reminds me that some of the numbers that I have chosen are somewhat arbitrary in regards to where I chose to divide, which may or may not be eligible for better formulas rather than my having had chosen some of the dividing points)..

Maybe there is a better word?  but it seems that I had likely gotten that word (whether subliminally or otherwise) from the idea of a retirement account, and the reference to a withdrawal rate of 3% or 4%, which means that there is withdrawal from the investment and use of the funds for various kinds of consumption and/or income.

Historically, we could look back and maybe put in the date of December 17, 2017 and we can see that the tool would have had authorized withdrawing 59 months in advance based on a 1,491% difference between the then spot price and the 200-WMA, but even if the person used such guidance to have monthly living expenses for 59 months, the bear market of 2018, 2019 and 2020 did not last even close to 59 months, so there could have been a determination at some point to use some of those sold months to buy back in, even in early 2019 (between April 1 and the end of June), there could have had been a decision to use some of those extra sold months (the 59 months in advance) to buy back some BTC.. and then reenable the ability to use the tool again.. since by the way, the idea of cashing out in advance means that you cannot sell any more (or withdraw anymore) BTC for all of those months in advance that you had withdrawn absent either using some of the months to buy back BTC, or if the BTC price goes up above the number of months in advance that you had sold in order that you would be authorized additional months to sell (or withdraw more). 

That sounds interesting to send alerts and of course we are mostly thinking in terms of alerting for possible sells (since this is a selling tool), but once such a tool is created, it could be used in either direction (meaning for selling and/or for buying).. so I am not sure how difficult it would be to add some kind of a tool like that, but it does sound interesting as a concept...

On the other hand, wouldn't the user have to provide some kind of data such as e-mail or sms.. and then would we be able to blindly interface with that, without collecting any user data?  I think that we are probably a bit nervous about any kind of collection or retention of user data.. at least at this point.. but of course, with discussions of monetization some times there can develop trade-offs to weigh differently with the passage of time.
