Combination Telegram -> Inexperience -> Desire for quick earnings = loss of money and time.
The idea that some with the apparent intent of persistently promoting “crypto is magic internet money” has only served as an ideal platform for all these scammers who literally prosper sitting in front of their computers and waiting for naive people to fall into their trap. For anyone who can't tell good from bad, my advice is not to use Telegram and some similar apps - nothing good will come of it.
But indeed now some information from telegrams and official projects, most admins answer there, so the most important thing is to be able to distinguish which ones are real and fake, unless beginners can stay away from telegram because all sources of fraud start there.
Only naive people are targeted by scamers to fall into their trap, IDO is now much in demand because of the sizeable returns so maybe the scamers now continue to attack things like by creating fake telegram groups.
But it's good the OP has shared it here. I will understand better.
