If everyone traded, the financial market would become extremely volatile and competitive. With millions of people constantly buying and selling, asset prices would change rapidly, generating instability. Liquidity would be high, but the risk of speculative bubbles and sharp declines would also increase.

Many inexperienced people would lose money quickly, as trading requires knowledge, discipline, and risk management. Algorithms and professional traders would dominate the market, putting beginners at a disadvantage. Furthermore, the real economy could be negatively affected if people prioritize quick profits over productive work.

On the other hand, massive access to trading could promote financial education and the democratization of markets. However, if it becomes a trend without preparation, it could lead to personal and collective economic crises.

Governments and regulators would need to intervene to prevent abuses, fraud, and market manipulation. In summary, if everyone traded, the world would experience a mix of opportunities and chaos, where only those who are well-informed and prepared could thrive without risking their financial stability.
