CMC is using the price from the exchange with the highest 24 hour volume. Just look at B3's markets tab on CMC's site. Right now Yobit has the highest trading volume because Coinexchange is still having issues, so you will see that the price displayed for CMC matches Yobit's. Also, Yobit's price is per KB3, that's why it is high. Coinexchange is still using per B3 pricing.

But it will definitely take a couple weeks before B3's price goes up. The problem is, there are so many billion coin wallets out there that just keeps dumping at the lowest price (the #1 wallet is probably the biggest culprit here). Those wallets are also probably staking, so they are replenishing their coin supplies at the same time. It will take a long while before those wallets get depleted enough for B3's price to recover.
