We all know that scams are common in Crypto space, people wanting to make a quick buck, some are in desperate need of funds or aren't technically well versed. Scammers prey on these people.
Common scams are like , Send me your ETH, I'll double it in 24 hours something. You ain't getting a penny from that. Next one is Impersonating some officials of the wallets they use and ask for seed phrase. If you give your seed phrase, boy you are screwed. Also there will be fake ICOs (Initial coin offerings), which are 99% fake , they say they will give you the coin at a very low price than its actually it's, they extrot funds usually between 10-100$ , if people are dumb, then even more.
The Groestelcoin Airdrop Scam:
Groestelcoin is an OG coin launched in 2014 as a Proof of work coin which would be used for day to day uses like transactions etc, at a fraction of fee than Bitcoin.
Now here's where our boys come to play. A youtube recommends an Airdrop bot. I played along and completed the tasks which were joining 3 groups. I would get 333 GRS (about 250$). And upon each referral I would get 30$. It was like a ponzi scheme but badly executed, for me. But the group had over 70k users.
This was the airdrop group , I'll drop the bot: 
Now the another group was the 3x, 5x crypto shit:. 
It was all set, they even posted some proofs which I think are probably fake, they may be their partners in crime. 

Now the scam is simple. You Invite 3 more people to be eligible for the Airdrop. So I invite my friend Jamal and 2 others. So that I will be eligible for the so called "airdrop". Now next day they start the payment bot, in which you enter the amount of coins you have and your wallet address. It was fine until this. Here comes the real deal. 
These all are about 10$ which they say are ' transaction fee' ironically for the coin which was designed for low transaction fees. Now people are dumb as fuck, they must have thought 10$ is not a big deal for getting 250$ i.e 240$ profit. I decided to check Etherscan ( I'll give the links to the transactions at end) ,and lord I could not believe my eyes , take a look yourself 

And lets not forget about Tron scan. 
Its around 2k usd , I only took recent transactions, Way more in Ethereum and BSC. I will give the scammers wallet address at the end of this, become a Sherlock and trace the transactions. Until they don't convert it into Monero or some Privacy first cryptos You should be able to trace.
Now these people on telegram are so desperate to scam people, they send messages like this given below 
Now humans hoard things in times of scarcity. Some may have actually sent them crypto when they told they were running out.
I feel bad for the people who paid them. Also a bit angry , no you shouldn't be angry at people who don't even have IQ of a toddler. They really thought that some random stranger would pay them money? Fuck man , even your friends won't give you money.
Here are their wallet address to check (not to pay you dummy) :

These stupid cunts don't even know that a memo is required on Binance chain to transfer crypto.
I think they are some good scammers based on their transactions history. It's a quick buck for them, while you lose your hard earned money.
I'll give the links to tronscan.
TRONSCAN , Many payments are coming in from the scammers wallet.
Guys check it yourself in Blockchain explorers you may learn a thing or two about transactions and may help you in finding your transaction when transferring crypto.
Outro:
Finally , If you just use your common sense that no one will ever give you anything for free, most of the scams can be avoided. So remember that and stay safe.
Update:
Telegram officially declared it as a scam:
