Take a look at this:

Over 27 MILLION STEEM worth over $100 MILLION USD is stored in this single account. Now if you look they only use this account to store EVERY client's STEEM and SBD in. They do not create content or posts or provide anything on their channel. This account I concluded is where Bittrex stores ALL STEEM and SBD. This is at least from my understanding, HIHGLY insecure, and here is why:

Keeping a "hot" wallet ensures that clients can withdraw their coins without a human involved. BUT this also means you must store the key somewhere that is accessible to the internet and create a piece of software to handle the withdraws. A hacker simply needs to find an exploit in your software OR the server in order to drain the hot wallet. THIS is why SMART security for exchanges requires a cold storage protocol where the bulk of funds are kept offline and verified and processed by humans.

We have seen exchanges hacked MANY times and for bittrex to basically store $100mln payday in the open with almost no security is insane! All someone has to do is figure out how to exploit their server OR their withdraw daemon and in seconds they can drain the entire account!

Simple best practices like the ones I outline for other coins help prevent the ability for theft BEFORE it happens! https://steemit.com/steemit/@bigdeej/how-i-secure-cryptocurrency-for-under-usd1-creating-a-cold-storage-locker

Let's make sure this doesn't happen and the only time you read about this issue is here BEFORE the coins are stolen! Hackers only need to be right once, security experts must ALWAYS be right! If you agree with me and are a @bittrex customer please reach out to them about this concern and push them to adopt a cold storage policy for their STEEM and SBD! They should not be keeping all their client's coins as a target in a hot wallet EVER!
