One way to absorb the short selling pressure to bitUSD is to throw more bitAssets on the market !!!
Think about it! The only way for someone to "bet" for BTSX if they don't have fresh money/BTC is to short a bitAsset....
Right now there is available only bitUSD, so all the pressure from the BTSX Bulls go there ... If we had bitCNY,bitEUR,bitBTC etc. the pressure would absorb "equally" to all...
so the market peg would be closer to parity for each of one, at least it would helped to some degree...
EXAMPLE:
bitUSD = -30% distance from parity point
bitEUR = -20% distance from parity point
bitCNY = -10% distance from parity point
so a smart BTSX BULL that want to short a bitAsset because they think BTSX will rise 50%, will likely short bitCNY
so the end result on profits would be 50-10= 40% profit (when bitCNY gets 1:1 pegged vs CNY)
instead of 50-30= 20% profit (when bitUSD gets 1:1 pegged vs USD)
I know I have oversimplified my thought process but I wanted to give the idea...
