Just like the title says, I was back testing some regular trading sites today. And I saw a pretty interesting one which caught my attention. They had claimed to give free 0.043 BTC upon registering as a welcome gift. I was thrilled and wanted to see for my self. I followed through their sign up process, using some random emails I just maneuver,and it registered me without any verification. So yes, it was true. I saw the 0.0043 BTC welcome bonus. And wanted to try if it were withdraw able. I already knew the only out come of this, which was obvious from the very beginning. I clicked on withdraw and added an address I don't use. And then I burst out of laughter to see that they had requested a deposit of 0.025 BTC before I would be able to withdraw the bonus.
First calculate 0.0043 BTC, it's about $250 with the recent pricing. Who would give you that for free?. Absolutely no businessman would be doing that kind of carless giveaway just as registration bonus. That's the first red flag.
It's notable that some people are still very naive and greedy and would definitely fail for such trap nonetheless. You're informed and that saved you. People in very remote countries would see it as a cash out and fall for it only to regret later.
One thing is certain, if greed doesn't take over you and you're someone that questions possibilities, even in your naivety you'll not be scammed easily. The greedy ones are the major target of scammers.
