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.
I think that if Bitcoin is a relatively new class resource, it would be reasonable if an investor decided to sell after 4-10 years. Because many people want to cash out the quality of life and to improve the quality of life and to think about leisure plan.I see this your statement here like someone with a myopic idea and thinking, because you can't just be selling off all your holdings just because you think that you have hold up to a circle or more, 4-10 years is too small in my own opinion to get something huge from your investment that can change your financial status forever, no, it's only if your stash of Bitcoin is very huge that you can get something good out of it, because in my own perspective, the best way to approach Bitcoin investment is to go through your accumulation stage first, true the dca accumulating strategy, which might take up to 10years or more , then after then you can decide on the number of years you can hold, after that time has elapsed, you might decide to start taking profit, but take note that selling off all your holdings, something you use years to accumulate and become a no coiner overnight is not wise in my own opinion , you should be taking profit gradually, bot selling all at once.
