*Write on Binance Feed and earn:* There is a possibility of earning $0.50 to $3.00 per post, but it depends on how good your posts are, how many people view them, and how much Binance is paying for this program. Writing two good posts a day and earning $1.50 or more each time *may be possible, but it will require time and effort.*
*Learn and Earn Quiz* is really a way where you can earn *free crypto* by watching short videos and then solving quizzes. Earning *between $0.50 and $1.00 per quiz is possible*, but the number of these quizzes may be limited.
*Binance Task Center:* It is *possible to earn some crypto* for simple tasks like creating a Web3 wallet or visiting a promo page. However, these are generally one-time tasks and do not provide a consistent income. What you will find in mysterious boxes is also uncertain.
*Overall:*
*Earning $2.75 per hour or more: this claim *may be exaggerated*. If you work for 15-30 minutes a day, it will be challenging to earn that much consistently. Some people may earn more by using "pro hacks" or participating in seasonal campaigns, but this won't be accessible to everyone.
*No investment required:* It is *true* that in these methods you don't need to invest any money from your side. You are using your time and the internet.
*Summary:*
These methods of earning free crypto are *real* and you can *make some money* from them. However, the claim in this advertisement of earning $2.75+ per hour might be *overly optimistic* and there is no guarantee that everyone will earn that much. How much you earn will depend on your effort, availability of time, and the opportunities available on these platforms.
Therefore, it is better to consider it as a small source of extra income rather than a way to earn a large amount of money immediately.
