I received a direct message on Discord from @Landon8300#9797 today at 16:09 GMT declaring that I'd won a cash prize draw from the Bitfynex (not Bitfinex) cryptocurrency exchange, a portion of an amount totaling $255,000. Instructions were given for me to register to bitfynex with a .com internet code (can't post web links here, apparently) and to enter a 12 letter promo code.
The code was alleged to have delivered $5255.58 in bitcoin to a wallet in my name on that site. I was unable to withdraw the value to my Bitcoin Wallet because a minimum of 0.1 BTC is required, the site declares, for withdrawal.
Is this a legitimate site? By googling, I can't find much of a digital footprint. And I'm quite new to cryptocurrency.
