We usually think of “investment” as giving effort or money to someone. But investing is more about exchanging what you have for some value, and the object of the investment has some worth rather than just giving something away. Some exchanged values can be monetary or moral. If I swap my cash for moral and social benefits, it becomes a religious or social contribution. However, if the object of exchange is an asset with a specific monetary value or potential for profit, it is an economic investment. The world is designed to facilitate some form of value exchange. The main idea of investing is to trade low volatility for high volatility and then switch back to low volatility over time. The former is called an investment, and the latter is called an exit. Cash tends to be less volatile, while stocks and digital coins are very volatile. By exchanging assets with small volatility, stability is maintained, but wealth is not necessarily increased. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
