It's quite easy to run a bot that places an order to front run other orders. It doesn't need to be an inside job. Anyone with a Bittrex account can do it by adding and removing orders using API calls and making them relative to other orders.
Even with my rudimentary python knowledge I managed to get a bot running on Poloniex a couple of years back. I can see how these can be annoying for those placing orders manually.
AH. I see. Oh jeepers.
I might as well kill myself now. It's just not in my nature to act like that, so no wonder I'm always losing. Have fun with your savage selves, humanity!
I don't think purchasing coins/ trading needs to be that complicated for most people. Just decide the price you want to buy/ sell at and place your order accordingly. Sure people may front run occasionally however it shouldn't make much of a difference if you're not day trading or running a bot.
