Blackmarketed refers to the action of selling goods or services illegally. Its antonyms, on the other hand, are legal and legitimate. Legal means something that is authorized or allowed by law, while legitimate refers to something that is in accordance with established rules and standards. So, if a product or service is not blackmarketed, it is legal and legitimate. Other antonyms for blackmarketed include lawful, authorized, sanctioned, permitted, licensed, and regulated. It is important to opt for legitimate and legal options rather than resorting to blackmarketed goods, as it not only poses a risk to one's personal safety but also contributes to the growth of an unregulated and unlawful market.
