Sunday a week agio i got scammed: A person identified (impersonate) himself as another (a dev of an altcoin) and after a longer chat and without other options to buy their coins I trusted him and send btc to an address he mentioned. I should receive the coins in return. Earlier this went well with another not impersonated account. I learned to double check ID#!
It should be very helpfull to mention the ID# after the name in chats as you do in the profile (when rightclick on a name and select profile)!
