Could be due to Hive-hype. Lots of people ( or just a few whales, soon to be called queen-bees ;^) ) want to get their hands on as much HYPE coin as possible, but they may fear that it'll be hard to acquire through exchanges. So, a work-around would be to buy as much STEEM now in order to get the 1:1 airdrop. Kinda like a loophole to avoid waiting for exchange listings.

By the way, here's a question for you guys: *I noticed there is already a coin called HIVE. Does this cause a probable for listing sites such as yourself? Having two coins with the same name / ticker could be wonky to work with, right? I've always been curious whether or not cryptos had to come up with unique & original ticker symbols.
