Example usecase
Suppose shapeshift wants to advertise
Currently - example 0.1 btc (or 10,000 POST ) for an ad .
-------------
1.Shapeshit will buy post at 250 sats , and the altcoinboard will accept it at 1000 sats ..
2. Supply from exchange will be depleted!! and Shapeshift gets 75% discount!!
I think that's a good thing, cause advertisers have to buy POST, which is gives POST permanent buy support.
