SBD can't hold over 7$ indefinitely. Cos it's drives up prices of Steem - only mean of producing SBD. And when a Steem price rises, ammount of printed SBD rises with it. This driving a SBD price down.

So, short term spike in SBD price is just a gift for a platform, but it will fall to 1$ in long term inevitably. We must not be afraid of this disbalance. But the market is crazy indeed - time to make money! )
