As I checked blocktrades a few minutes ago, there was no more STEEM featured on the coin list. Is blocktrades canceling Steem? We don't know, but before panic let us search for this event in the past and we see it happend several times, because their Steem wallet went down or the storage for the Steem Wallet went low while they were on vacation. We still don't know, but it's most likely that it will come up again, as there is no actual reason not to support STEEM.
@blocktrades ?
