Where the heck did you get that Bittrex runs their own bots? Maybe they do, maybe they don't. But head over to the marketplace and search for C.A.T. It's a bot anyone can buy and run to do just what we're seeing. I can guarantee you that there is more than one bot running on a lot of the markets out there designed to accomplish different things. Blaming bittrex (or any exchange for that matter) for what other people are doing is just ridiculous.
Whether it's bots or some guy coming along and manually putting in large buy or sell walls, market manipulation is simply the way it is and that will never change given money is involved.
They do run them or they don't. The fact is that their bot system constantly devalues the price of all newly emerging cryptos.
I know that there are many other bots out there.
If it is someone devalueing the price then wee need more major exchanges to deal with LTCD to stabilize it.
