I lost all Funds in Vitalik Ethereum Scam in Bitcoin (Crypto Currency).
Excuse me from asking, but did you put your thinking cap on? So, a website says that if you send money, you'll get the double in return. How could this not look suspicious to you? Why one couldn't simply empty the whole “faucet” of free money by re-sending what he got in return? How couldn't you make your research that Vitalik did, indeed, say that he'll do such “giveaway”.
Don't leave greed poison you. Use your common sense.
