If you are not aware yet, Bakkt has launched a few days ago and some scammers out there are taking advantage of its popularity. They are doing these BTC, ETH, and maybe other giveaways to trick unsuspecting beginners. THERE ARE NO BAKKT GIVEAWAYS. Stay safe and do not fall for these old scam tactics. Always remember not to give away your private keys, mnemonics or seed phrase to anyone.
