Speculator

Speculation is a skill developed by individuals, offering a way to engage in business and achieve growth. While it can lead to profits, there's also a risk of losses, making it a risky endeavor. 

For instance, a person may buy gold on Monday and sell it on Saturday to make money. This practice involves various participants, such as market makers and investors, who employ different trading strategies. They play a significant role in future markets and are often referred to as primary participants.

Speculators experience many ups and downs in life. To succeed in speculation, it's crucial to focus on moving forward and not dwell on past setbacks.
