Start with your purpose
Define what the money is for, when it may be needed and how much uncertainty you can reasonably accept. A long-term goal, an emergency reserve and short-term trading capital should not be treated as the same pool of money.
Understand the product before the price
Learn how the product works, what can create a gain or loss, how easily it can be sold, and which charges and taxes may apply. Read the official product and risk documents before acting.
Build safer market habits
Use official sources, enable strong account security and never share passwords, PINs or one-time codes. Treat unsolicited tips, urgency and assured-return claims as warning signs.
