Poloniex and Bittrex announced full KYC and more coin delistings of altcoins on their exchange.
Of which many predict more than 80% of coins there.
Plus if you are in NY double blocking as you can't use it those there(now/soon).
As Steem is not on Coinbase nor Kraken the chances of it lasting on those exchange are slim to none.
Poloniex is also a shit exchange so using it is like 0.
Bittrex while better is getting worse and worse and in some reports are getting lawsuits against the :(
While I not saying Steem will be 100% gone from there, there no big money lobbying it to protect it. Steemit inc could but I not counting on them :(
