This all happened so quickly. I feel like 2-3 months ago there were a lot of people on Steemit proclaiming the end of Bittrex, which they said was about to go down and definitely terrible to use.
Now fast forward and Poloniex is the villian, and everybody is praising Bittrex. oof!
Maybe it's just my imagination, I don't know. For now I am also keeping off of Polo, but who knows what will happen in another few months.
Well definitely a secure and highly functional DEX is soon to be a requirement. I think Poloniex just has a pretty good UI.. (ok, and volume)
