#CryptoFees101 The Three Age System is a way to categorize human history into three distinct periods based on the primary materials used for tools and technology. The three ages are:

1. *Stone Age*: Characterized by the use of stone tools, this period spans from the earliest human ancestors to around 10,000 BCE.

2. *Bronze Age*: Marked by the development of bronze tools and metallurgy, this period roughly spans from 3000 BCE to 1200 BCE.

3. *Iron Age*: Defined by the widespread use of iron tools and technology, this period begins around 1200 BCE and continues until the advent of modern industrialization.

This system was first proposed by Danish scholar Christian J. Thomsen in the 19th century and has been widely used in archaeology and anthropology to organize and understand human cultural and technological development.
