One thing I know for sure is that STEEM will be more than $5 very soon in all the exchanges.
we had similar situation with Polneix, where they disabled STEEM withdrawals for a while and during this time STEEM price on Polneix was so low compared with other exchanges.
Also I know some Chinese rating agency has ranked STEEM as their second best Blockchain and lots chinese millionaires have close connection with Bithumb and I'm sure some people really know the true value of STEEM.
Also I'm personlly happy at least Bithumb is optimistic about STEEM's price even if this is kind of price manipulation and Coinmarketcap.com should do more to stop these kind price manipulation to appear on their website..
NOTE - I'll post my answer to my blog and if somebody would like to answer respond please answer the original question on Musing!! and please do not comment on this post. Hope you understand
