If you plan to set a target in order for you to accumulate and build a house, what if you build the house and empty your portfolio. Your house wouldn't give you the kind of profits that your bitcoin investment will give you in ten years after you have sold your house. It's not a good decision to sell all your bitcoin after you have spent a very long time to accumulate and build your portfolio, and you will become a no coiner. You can sell part of your bitcoin investment when you have reached an over accumulation stage using a sustainable withdrawal method in order to keep your bitcoin investment healthy.
It's very simple if you look at it from a plain view, I mean an asset that can't you profit is probably a liability although that's my personal view on the case scenario because I can't afford to sell all my Bitcoin and get a house although it's a necessity for man but if I have somewhere am staying currently that isn't all that choking then what make such move, I mean selling part of my Bitcoin is not actually a bad idea in a case scenario where the price of Bitcoin have reached a point of interest for me but still selling all and starting from scratch to gather up is not a good idea at all instead sell part and use because that saved up Bitcoin will get you more profit in years although if you are into real estate and buying of properties then thats a different case as that investment too is something quite considerable.
