I consider bitcoin to be a lifetime investment, so once you reach overaccumulation status, then you would start to have the option to sell within the overaccumulated amount, and so I do not consider bitcoin to be an asset in which you might spend 4-10 years or more accumulating it and then you sell large portions of it or even all of it.
After reaching the accumulation limit of more than say 10 years of doing it and bitcoin is already in the range of $500K, it will sell bitcoin partly for sale because the goal has been fulfilled from the initial investment plan.
So I will not continue to hold for as long as possible, there is a time to sell but now is still not the time because it is still planting and until the harvest arrives after 10 years.
You are absolutely right there is always time to sell. And I don’t think that we can keep holding for a lifetime, The primary goal of someone that is investing in bitcoin should be accumulating for as long as 4-10 years then at that point you have achieved your goals and you can try selling little by little so you don’t have to sell all your investments. At this point a newbie should be more interested in accumulating and getting to over accumulating.
