Go short/long at the same time. If the short "wins" then borrow real USD to buy the USD necessary to cover and claim your profits, then repay the real USD from those profits. If the "short" loses, cover with your long position and keep your long yield.
This will give you a position better than just holding BTSX. The trick is that this position requires your "short" to be matched which means you have to buy at or above the median feed. Ie: supporting the peg *and* you must pay more than all the other shorts. The good news is that if people do this then it will end up supporting the PEG *AND* paying a high yield on USD.... thus greatly increasing demand for USD *AND* thus increasing the value of BTSX which then maximizes your real investment in BTSX.
I think this needs some clarification as it may be misleading some.
If your short wins, your bitUSD long loses. Whatever you gained by going short, you lost by going long.(equally Vic-a-versa) All you net from this deal in either case is the interest earned on the bitUSD long. Also, If it requires you to buy up the bitUSD order book to enact this trade then you've lost this net balance as well, and your overexposed to bitUSD.
It does support the peg though, and this should lead to higher BTSX valuation, but don't think that your increasing your BTSX exposure with this plan. If your simply interested in capturing the interest on bitUSD or supporting the peg, this is a good way to do it with little risk, provided you don't have to buy up the book to enact it.
Going short/long at the same time is equivalent to holding BTSX with an option to double your stake at todays prices at any time.
I don't think this is true. The second half of this 'double stake' was spent in the initial trade to purchase the bitUSD to balance the short.
Please correct me if I'm wrong.
