So far it seems to be a Telegram channel dedicated to some sort of card counting, which is not necessarily an attempt to scam anyone at a first glance.
Though, It would be silly to assume cars counting could give one an advantage against the house when comes to blackjack, it is common knowledge casinos use multiple decks of cards in live casinos in order to deter those who count cards to increase their leverage against the house.
Probably there is some scam behind all of this, but I would not give deeper. I prefer just to be cautious, there are a lot of scams in Telegram, that is for sure.
You are very correct, this is just a way that some new people can be deceived. The house are in a way that gamblers will just lose at the end, people should not be deceived. When I see a services like this, I see them just like scam, but you are right that money is not involved, so it does not mean. But people should be very careful, when it is leading to what will let the
aypay money in one way or the other.
