What are the constituents of investors?

Broadly speaking, there are many investors who raise money from relatives and friends in the early stage of starting a business, from small to large. Even if relatives and friends are investors, if they are professional investors, there are also high-net-worth individuals who specialize in various types of venture capital. From the institutional point of view, there are various private investment funds, industrial funds, government guidance funds, Public Offering of Fund and so on. Other enterprises will use their idle funds to make some foreign investments in order to maintain and increase the value of assets or expand the industrial scale. Anyway, as long as you have the ability to invest abroad and aim at a certain income, you can call it an investor, and everyone can be an investor.
