A 200x increase would put the BTSX market cap at $16,000,000,000 USD. I don't see that happening all in one bubble cycle. I'll be happy with a 5x increase over the next year or so.
BitShares is currently trading at over 5x its value of just one month ago...things move fast when something truly revolutionary is afoot. I personally believe we'll all be caught off guard at how quickly things explode if BitYield works as planned and an impressive trading software suite rolls out. The potential here is absolutely monumentally enormous...can't wait. 
The velocity of crypto-capital is unprecedented.
Moving value from fiat -> BTC has been painfully slow, and still is for the majority of folks.
But even with a severe on-ramp handicap the increase in BTC market cap over the last five years has been breathtaking.
Moving value from BTC -> BTSX takes minutes...
I don't think we can underestimate the velocity with which value can move into BTSX.
Hell, it is possible to hit a cap of $1bn in few months if a substantial marketing campaign is rolled out.
At the very least, why not hold bitBTC and earn some yield?
BTC holders don't have desert for the BTSX camp... they can maintain their portfolio allocations and improve ROI.
Once there is depth and solid peg I know I'll be moving some value from BTC to bitBTC.
Just need to get the platform stabilized, a reasonable feature set in place and then get the word out.
The ride could be epic.
