A few months ago, one of my friends sent me his invite link to this project. This project claimed a new airdrop called TONEE and also they claimed that their mini telegram app also rewards people with TON coins (which is native to Telegram's own chain).
I had almost 1.2 TONs based on what they said on the app, but for withdrawing the coins, you needed to buy a "booster".
Most of all these telegram apps are turning out to be scams, people are no longer making money from them again, most of the airdrops that happened recently turned out to be dust, what most people received isn’t really worth it, and most of them do request for users to either make some transactions or for them to pay some amount of money to increase their rank, but at the end, what people do receive sometimes is not even up to the amount spent on the transaction or amount spent to increase rank.
I know nothing about the project that you are talking about, but immediately they ask you to pay before you will be able to claim your reward. It looks suspicious, you shouldn’t have paid the money. When participating in an airdrop, you are not even supposed to put money in them, if you don’t put any money in it, if the airdrop turns out to be a scam, it’s not really going to be painful compared to when you put money in it.
