I mean the balance between shorters and longers are dynamic,
you can't give a simple rule to encourage shorter or longer
but the free market have already give the best direct to keep the balance.
when you see the bid price of CNY/BTS market is much high than others, it means we need encourage CNY holders, you sell BTS for CNY then you get profit.
when you see the ask price of SILVER/BTS market is much lower than others, it means we need encourage SILVER shorters, you borrow SILVER, sell for BTS, then you get profit.
if you want to get rid of the price change risk of BTS, you just need to borrow CNY and SILVER, sell SILVER for CNY, arbit bot will take your order, and you will get your profit.
be a market maker, keep the balance, increase the liquid, you create value for Bitshares, and you get profit. this is the right way.
