TBH I don't understand all the bittrex hate.  Just because they host some coins that become scams, does not mean that they are bad actors.  People are free to make up their own minds on what they invest in. 

It's too bad that the past year has been an explosion of scams in the altcoin world but that is certainly not the fault of bittrex.

They continually update their website, albeit not very user friendly but they at least do it more often than the other major exchanges.
