Litecoin up - Poloniex account balance down

Litecoin up - Poloniex account balance down

I 'm not sure what is going on but yesterday I was on Poloniex and my account balance kept decreasing while Litecoin was coin. Now I had Steem and LTC and at the time they were both rising and i kept on looking at my balance but it kept decreasing by like $20-30 at a time. I know that Poloniex has been experiencing some DDOS atacks lately and the site has been experiencing some frequent crashes. If anyone out there can give an explanation as what the heck is going on on Poloniex, I would definitely appreciate it.
