Bittrex sent some steem to steemitinc. I guess they were able to reacquire some of the contested tokens from bittrex.

That's 8 and 6.4 Million Steem tokens plus more to poloniex and huobi.
Steemit sent some to Binance.
Who knows what is behind of all that movement and who is doing that.
It is still a good thing, if those tokens we to be all sold then sell pressure will diminish and steem token price will creep up.
