I found several sites that are for giveaways, one is giving an iPhone 11 PRO MAX, the other is giving MacBook Air last Gen, You can join that giveaway for 1-5$, but at first, you have have to fill a blank about yourself, Is it to collect data, or to know where to send the prize?
Also, I heard that is good for business, but I don't know how good is it?

Any answer is welcome.

Nobody will ever be generous enough to give away $1000+ without gain. It is likely a scam.
