I wanted to participate in the Iagon pre-sale. I joined what I thought was the official Iagon telegram. Turned out it wasn't. I followed the instructions on the pinned message, which directed me to send ETH to a specified wallet address. Turned out it was all a scam, and I lost 5 ETH.
Really sucks. The lesson is be careful out there.
I feel sorry about your lost. Next time think twice before you send money to unknown person because you did not know if it is a scam or not. If you really want to joined in a pre-sale be careful to choose. There are lots of scam out there and you must be aware. You should know that there are no free in crypto world even airdrops.
