There's a new kind of cryptocurrency scam on the horizon and it's messaging people on discord. Random people are told they've won free bitcoin with a promo code. It all seems harmless when you register with the site and put in the promo code - it appears that the money is present. However, upon any attempt to 'withdraw', you are asked to verify yourself by requiring a deposit of no less than 0.01 bitcoin (currently ~$600 USD). People have tested this out, only to find that their account is shut down shortly afterwards or, upon request to withdraw their winnings, it never arrives. Never accept prizes with a price.
