Yes, there are those who think differently about diversification. While some understand this diversification as only crypto, some diversify by making gold, real estate, crypto and other investments together. I actually think this situation is related to financial strength because a certain level of financial strength is needed to invest in different investment vehicles. Those who do not have this financial strength use their investment right by choosing a single investment.
The financial capacity of an individual might determine how he manages his investment. But diversification could be done even with limited resources. Since Bitcoin can be bought in bits, someone can buy based on the funds available. The same thing can be applied to gold and other precious stones. As for real estate, instead of focusing on assets in urban areas that are expensive, teal estate assets in rural or semi-urban areas can be cheaper to invest in. You don't need to have a fortune to diversify your investment.
