Hi guys I have joined crypto since a very long time maybe form 2018. At that time I have had no knowledge and I went to join some airdrops but earnings was very low. Here I met many new telegram members and everyone trying to Scam with with me.
From your post OP which talks about the airdrop here, its not only about the scammers that trying to engage new users to invest but also they drop fake airdrops when you click it, it will drain your assets. It would be better to surround yourself with a group with good background because seems like you can already tell the difference about scams and legit. I also salute you from trying out different way of earnings.
Mostly of them are from USA, Nigeria and UK. some people use Women voice and they trap new people to join investment scheme and other such things.
As telegram is much more secure than any other Social media that's why there are a lot of Scammers than any other platform. And I think that sucks. And these are the people in which new People don't believe in crypto and we have to change it.
Of course it will be a group of scammers so they can easily work together to scam newbies like acting that they are like you trying out airdrops. If people think already think that telegram is secured then they will let their guard down causes them to get scammed. You could simply report them online for the others to be aware of specific group or person to avoid them.
That's a good effort for your security, you could actually edit your privacy settings to avoid getting unknown messages from unknown numbers. It already happened to me before but once I edited my settings its all clear and you could actually use telegram without scammers but always double check.
