Well, it all started yesterday when I received a message in Telegram from this supposed exchange.

They told me I received a prize in Bitcoin of approximately 0.38 (about 14 000 USD).

The message I received from them told me that it was very easy to withdraw funds:

   Нow уou can сollect уour winnings?

   1.Register аn aсcount оn thе ехchаngеr: http://bit.ly/xlmcahype
   2.Gо tо settings
   3.Yоu can аctivatе thе рromo cоde on thе «Sеttings» -> «Referral prоgrаm»
   4.Withdraw BTС tо your addrеss
   5.Dоne

But it was not as easy as expected. I can only withdraw funds to external addresses if I make a deposit of 200 USD from that address.

It sounded suspicious to me. So, I am not going to make a deposit to try and get that 0.38 BTC because I probably will not get it (but surely they will get my 200 USD).
