What are crypto competitions?

Crypto competitions, also known as crypto contests or crypto giveaways, are events organized by cryptocurrency projects, exchanges, or other entities in the blockchain space. These competitions typically involve participants completing specific tasks or challenges in order to win rewards, such as cryptocurrency tokens, NFTs, or other digital assets. The tasks can range from following a project's social media accounts, retweeting or sharing posts, completing quizzes or surveys, or even participating in trading competitions. Crypto competitions are a popular way for projects to engage with their communities, attract new users, and increase awareness about their products or services. However, it's important for participants to be cautious and thoroughly research the legitimacy of the competition before participating, as there are also scams and fraudulent competitions in the cryptocurrency space." So, my question is: Can you elaborate on the different types of tasks or challenges that are commonly found in crypto competitions, and how participants can ensure they are not falling victim to scams or fraudulent activities?
