Also it is not compulsory that you take part of your bitcoin investment to diversify into other investments. You can use a different source of income to invest in other kind of investment and not from your bitcoin hodlings. This is why when you feel you have bought more than enough Bitcoin, you can them channel that money that you are using to buy bitcoin into a different investment to grow it so that let it not be that you are depending on only your bitcoin investment should incase the price of bitcoin goes against you.
I don't think any smart person will even consider selling his Bitcoin with the intention of investing the proceed in another business under the guise of diversification. That sounds irrational to me because I feel Bitcoin is among the best investment instruments I have seen. When people talk about diversification, what I understand is a situation whereby an invest set a target to achieve in Bitcoin investment say 1BTC or 10BTC, as the case maybe and after this has been achieved, the investors might decided to consider investing new cashflows at his disposal into another sector entirely such as stocks, real estate, agriculture or any other. This way, there will be no conflict in the wealth building process because it is well planned with the targets clearly defined. What I do not like is people investing in shitcoin and call it diversification; it is the same sector of which Bitcoin is the best among them.
I have a nice future plan about diversification such that when I hit my target in terms of Bitcoin accumulation, I will start investing massively in agriculture because farming is one thing I have passion for, to be able to grow my own food as well as profit from it. So this is a future plan due to limited financial resources, hence I have to establish my Bitcoin portfolio first before I start focusing on this long term dream.
