these giveaways on twitter are often more about the engagement farming for the twitter owner than anything else
it's nice because all have a really tiny chance to win but what they get in free publicity and organic reach is usually enough reason for them to share a prize.

There have been a lot of discussions about this, but I still wonder if you attract a lot of people (or a new audience) with posting these giveaways on Twitter/Telegram? They are dominated by bots and you need to be extremely quick and lucky to win a small prize. You will get views as everybody loves free stuff but I doubt it is really effective.
It is an effective way to attract people. We all know that many people love free stuffs may it be in the form of a reward from a contest or airdrop. More often than not, people will try to play with the giveaways making them to try the casino platform service if they have not registered yet. Aside from that, a company will not do things in repeatition if they find it not profitable. So seeing casinos making giveaways in a constant manners means it works well for them.
