I cannot say how realistic it is for a person to hold an investment for 30 years. Maybe for a young person who is 20-25 years old, it may be fruitful to hold an investment for 30 years or more. But I cannot say whether it will be fruitful for a middle-aged person to hold an investment for 30 years. The biggest question is whether he will live to enjoy his investment after completing the 30-year period. Even if he lives, there is a doubt whether he will be able to enjoy that money. If an investor's investment does not work for him, then I consider the value of that investment to be zero. I will definitely want to leave some part of the investment for my inheritance, but not the whole.

Enjoying the investment does not mean that you will spend and eat the investment money. After two cycles or three cycles, I will prefer to do real estate business with the investment money. This will give me a new identity and create a source of income after retirement. A 20-25 year old young man can prepare for his retirement by holding on to his investment for 30 years at the age of 50-55, so his long-term investment can be fruitful. However, I have a question about how fruitful a long 30 year investment will be for a middle-aged person who is about 35-40 years old, maybe this investment can be fruitful for his children. There is a question about whether you will be able to enjoy or transfer your investment at the age of 65-70, and even how much your successor will value your 30 year investment, this is definitely a matter of concern. So I would give the highest priority to 10-12 year investment instead of such a long-term investment.
