I would like to think that everyone knows that all telegram investing bots are scam, yes, some of them worked a bit or may have been paying you back, but you need to know that even in the situation which it don't just take your money and pay you back, it can turn scam at any moment because most of them works as a Ponzi Scheme. Sadly, there are still lots of people that doesn't realize this and want to make easy money, thus losing it all. If you don't know what a Ponzi Scheme is, it is a system where investors get paid with the money of later investors, it will end in one of two possible ways:
1-) Because the need of many investors, there could come a time when there isn't enough funds to pay everyone within the given period, so it ends up becoming a scam.
2-) In the other case, maybe lots of people like it and take many profits of it, and it spreads getting lots of investors, and instead of paying they just keep all the money, so it ends up becoming a scam.
So remember, everything that ask you for your money, promising wonderful returns, is almost certain a scam. So please don't fall in that and lets make the crypto world a safer place to encourage adoption.
