As long as you keep trying to prove that diversifying our investment in gold or silver is good, I disagree with you. Yes, bitcoin is a long-term investment. Before we can make a good profit from our bitcoin investment, we have to hold it for a long time, such as 5 years. But you fail to understand that since we have accumulated the quantity of bitcoin we intend to accumulate, it is not good for us to diversify our investments into another long-term investment, which should take the same number of years as bitcoin to give us a return. We should diversify our investments in something different from bitcoin so that we can use the money from the investment to solve our living expenses, and it will make us not to depend on our investment to survive or sell it in a hurry to solve unexpected problems.
Maybe it could be a good idea to describe why a bitcoin accumulator might start feel more and more needs to diversify as his bitcoin investment grows.
After thinking this properly, I think I can now understand why people do diversify in their investment. I noticed that there is usually a point where one feel the need not to also have investment in other asset especially physical assets to avoid the idea of "laying all eggs in one basket". Such diversification may not necessarily be because the physical asset is more profitable than Bitcoin, it could just be a hedge which is normal in business. Areas to diversify to depends largely on passion, knowledge and level of financial capacity. Some might have passion for real estate, some import/export which is popular in my place, some agriculture, the list is endless. The bottom-line is that diversification is not a bad business approach as it does not constitute any distraction to Bitcoin accumulation. Having been investing in Bitcoin for a while and have been able to get reasonable quantity of Bitcoin, I do feel the urge to also invest in other areas just as a backup and to also keep me busy as Bitcoin investment does not really consume much of my time.
What I do not consider diversification is buying shitcoin and calling it diversification. I know some people do this and think they are diversifying but I don't consider it a great way to diversify because Bitcoin is just enough to consider base on the low risk level and the high level of reliability it has. It will not be fine if what is supposed to be a hedge to Bitcoin to turn out as scam.
