You haven't done anything, you received that kind of amount? Isn't is suspicious already.
I don't know the exact reason why there are some people who are doing this kind of thing in Telegram, but avoid these kind of airdrops at all costs. I mean where do these people get that kind of money to just give it to random stranger for free? If it's Elon Musk, or Jeff Bezos or any rich businessmen out there then it's possible, but I don't think that they'll be doing this as well.
Overall, we already said that this is a scam attempt, and there's no way for you to get that money for free. Well, you can try if you want if you're too curious about it as long as you will not give anything that's personal for you, but just by looking at that picture, it's pretty obvious that it isn't real.
In case you don't know or haven't seen it yet, these scammers also use rich people to scam people, I've seen it a lot of times where they have a video of Elon Musk running either on YouTube or Facebook or elsewhere, they have a proper streaming setup where there is a wallet address for either Ethereum or Bitcoin and they are pretending like Elon Musk is helping people and he sends double the amount they receive on the given address, lol.
Surprisingly, a lot of people, who are new in the industry or in cryptocurrencies, tend to fall for such things, and they actually send some money to the given address and hope that they might actually get something in return, how naïve! So, these scammers are smart and they keep getting smarter.
