An advance-fee scam is a form of fraud and one of the most common types of confidence tricks. The scam typically involves promising the victim a significant share of a large sum of money, in return for a small up-front payment, which the fraudster requires in order to obtain the large sum.
Any Internet user knows this loved scam is very common, used actively all the time and has number of aliases, including Nigerian scam and 419 scam.
I was on my computer minding my own business when a bot approached me in Discord (that chat-thing gamers use):
Basically what they're saying, I'd get ~7000 € worth in Bitcoins by going to their scam-site, registering as new user and applying the given promo code.
Ok. For those whose bullshit detector wouldn't start dinging already think this for a second:
Why would a complete stranger offer you 7k€ in Discord!!
Being interested on their scam, I went for it. Clicked the link to their website, registered a new account, followed instructions and applied the promo code. Hey presto! I was rich!
I was a proud owner of 0.711 BTC. Serious money that!
Further following the instructions:
Obviously I wanted to access my newly found riches. Those precious Bitcoins were calling my name and I wanted to transfer them out to a wallet I controlled and could use them for buying new and shiny things.
Not minding the 0.005 BTC transaction fee, this is what happens when you try accessing your Bitcoin giveaway -price:
Now they're claiming my new account has been frozen, because they think I'm a bot. Thawing my funds would be easy, simply transfer ~300€ worth of my money to them! As I wanted to keep my own hard-earned money, I did not send them the requested 0.03 BTC. I'm 100% sure, they'll keep inventing "surprising" costs and other things requiring subsequent transfer of funds. I would never ever be able to access the fake-price they awarded me.
