SBD values were showing high on coincheckup and crypocompare as well. Although they are not exchanges, they have some form of legitimacy. So I'm not sure why SBD prices sky rocketed for a few hours yesterday. I don't think it was just HITBTC. Or was it the HITBTC prices influencing the overall pricing?
The issue is HITBTC has some coins like BTCP. U can't buy it anywhere else. I hope they are real.
I think what happened is these coin market reporting tools are taking price data from exchanges and merging the prices to make a consolidated price. Those tools are not smart enough to determine that a wallet is frozen and omit the data.
