It is generally illegal to use insider information for gambling or trading. In the financial market, trading on insider information is considered insider trading, which is an illegal act. In most countries and regions, the law explicitly prohibits securities trading based on undisclosed material information to protect the fairness of the market and the interests of investors. In the field of gambling, although the laws may vary from country to country or region, using insider information to influence gambling results may also be considered cheating or unethical behavior. Such behavior may violate the rules and terms of the gambling operator and lead to legal and financial consequences. If you are considering any form of investment or gambling activities, you should follow legal regulations and ethical standards to ensure that all actions are legal and fair. If you are not sure whether a certain behavior is compliant, it is recommended to consult a legal professional.
