Coinmarket showing the value of SBD almost twice as much as the original!

At this moment, Coinmarketcap is showing the value of SBD as $3.48 or 0.00045737 BTC. I was surprised to see the value of SBD that high, since for quite a long time, its value has been going down. Therefore, I was tempted to sell my SBDs, but when I went to Bittrex, it showed the value of SBD to be almost half of this at 0.00022935 BTC.

Then I opened the Markets tab for SBD in Coinmarketcap, and this is what I saw.

So, in most of the exchanges, the value of SBD is around $1.75. However, at HitBTC, it is $21.55! This obviously inflated the average price. Now, if you go to HitBTC, you would notice that deposits for SBD are disabled. So, you can't just send your SBDs to HitBTC and sell them there.

Having said that, the price of SBD has still increased a little bit compared to STEEM. I remember that at one point 1 STEEM was equal to 1.5 SBD, while now it is 1.387 SBD.
