The extension shouldn't be limited within 10 years but also as a lifetime process, not just accumulating for 10 years only. The process is for us to look in a long run, DCAing, sticking to our investment plans also not over engaging the process but developing a system that makes you consistent in your accumulation phase. If we treat it this way, we won't get tired but keep investing in our digital gold.
Its not out of place to invest in a much longer time (more than 10 years). Actually you can invest for as much as you desire, but why the pointers are between 4 to10 years is for your investment to be profitable for you, so you don't buy when the price is higher and sell in the dip. That's surely a loss. With that time frame, you'd have seen good gains and can decide for yourself whether to continue, or take your gains and quit. Bitcoin is always there to welcome you whenever you choose to return to investing, just that your gains wouldn't be compared to the one who perseveres for a longer time, maybe up to twenty years or more.
I'll advise that even after 10 years and you must've gotten your good profits, don't sell off, you can take of some part of your gains and invest into something worthwhile as a means of diversification, maybe agriculture or open a business that will continue catering for you so your investment remains untouched for another length of time and who knows, your investment can boom more than you expected and would provide you more funds to keep accumulating periodically. The goal is to keep increasing the portfolio for bigger and better profits.
I will not diversify my bitcoin into another kind of business by selling it after 10 years, because like you said, for your bitcoin investment to reach 10 years timline, it means that you have been able to accumulate a significant amount of bitcoin, which you should just relax and continue buying with any strategy that you feel is comfortable for you. This is because that is when the compounding profit have a high capacity of generating higher profits for you than before. If you sell some parts and diversify into another new business.
You will miss that compounding profit that would have been accumulating continuously overtime, which might help you reach your your fuck you status faster compared to when you sell part of it to diversify into another business. Another thing is that how are you sure that business will be able to give you profit within a short period of time that you started it. The business needs to monitored and during the early stage, it can take more money and more of your time to grow the business, and due to some inflationary problems a d government policies, the business might fail.
Lastly, the profit that you will make from your new business is four years with stress and hard work might not be upto half of the profit that your bitcoin investment, that you continue holding without selling a dime after ten years will give you after an additional of four years. Currently, I think Bitcoin investment should be one of the best, if not be best to give you a better profit than any other investment. So these are what we consider before thinking of diversifying. I am not saying that to diversify into another investment that is not on the same line with bitcoin is bad.
