Bittrex Email SCAM
I got this email from bittrex, it looks like someone hacked a bot to send out this email. This is a scam, never open your wallet address for anyone with their supplied link. They will just transfer out your cryptocurrancy into theirs. And you won't be able to do anything about it. I really wouldn't keep any money in the exchanges as well. Find yourself a good wallet. I personally use a ledger nano s hardware wallet. I don't like keeping my cryptocurrancy online where it can possibly be hacked.
That has nothing to do with Bittrex
