Sadly, the Upbit SBD price is not a "real" market price; it is created purely by automated trading by people trying to manipulate and make a profit with the SBD already residing on the Upbit exchange.

As far as I know, the ability (for ANYONE) to deposit and withdraw SBD to Upbit has been suspended by the exchange itself. Thus the Upbit price exists only within the closed loop that is Upbit.

It would be a bit like someone telling the world they can buy a new Rolls Royce for $1,000... but nobody can find the store, and even if you could, you're not allowed in.

If anyone knows differently, please enlighten the community.
