What they offer in the telegram channel make it clear that it is 100% scam attempt. They offer $100 bonus for those who make $100 top up and they also offer 50% gift for those who are investing. Something which is too good to be true should be considered as suspicious and we should be careful with it. I am sure people are smart enough these days and will not be attracted to spend their money in this kind of offer. The raffle itself is suspicious because people need to buy at least 1 ticket how much time is left . Honest raffle will inform it publicly without asking people to buy ticket to see such a basic information.
