I stand by my earlier comment, and if you are retiring, you do not want anyone exit scamming with your retirement principle merely because you feel insecure about whether you have enough to be able to cash out 4% per year or some other reasonable liquidation plan and still be able to largely preserve the value of your principle and to have the asset (in this case bitcoin) to appreciate in value enough to be comfortable with the amount that you are withdrawing.

Of course, if you are retiring, the longer your timeline, the more secure that you need to feel about having enough principle to last you whether for the duration of your retirement and that you do not have to go back to work because you failed to properly plan in term s of the amount that you have and the amount of your spending.   

If you anticipate your retirement to be 10 years, 20 years, 30 years or more.. then the longer the timeline, the more you need to be careful regarding how much you withdraw or if you go into retirement too early, then you might not have been ready for retirement if you cannot sustain your withdrawal amount..

I personally believe that $2million in principle would be sufficient for a lot of people around the world, because withdrawing 4% per year from a $2million principle would allow for $6,666, in passive income.. which presumes that the value of your various investments (in this case bitcoin) will appreciate on average at least 4% per year.. Personally, I believe that bitcoin can meet the at least 4% per year of sustaining its value or appreciating in value presumption without having to take 3rd party risks, and sure other people are going to make other presumptions or take other gambles, and they might end up getting exit scammed which will cause them to have less money in their retirement, presuming that they do not put all of their eggs in one basket. 

I personally do not have all my eggs in one basket, but I am thinking that bitcoin will constitute a pretty decent size of what is available t me, and my other investments by themselves are also enough to sustain me so bitcoin, for me, kind of serves as extra icing on the cake.  Of course, also, we live in uncertain times, so it becomes more possible that I will have to live off of my bitcoin, but my bitcoin is way larger than my conception of my basic needs.. so in any event it seems to be both good to have a cushion and also not feel that there is any kind of need to earn money on your bitcoin through some potentially problematic third party for the reasons that I already repeated several times.
