Never ever send any ETH/BTC to a wallet given to you within telegram or elsewhere by people pretending to be support/admin!
This information is highly appreciated as I have witnessed this on telegram. Most people that has a projects ongoing should also watch out for this scamming activities. I am promoting a project on the telegram and the admin put serious warning on this. Please always buy from the website of any ico you wanted to invest in. This will help in keeping your bitcoin or ethereum saved.
