^Interesting idea you got there, though facts don't support it. BTC price actually fell since the first IPO. If RENT worked as a hedge, share price should be higher.
But wait! That's not all!! You'll also receivefive paring knives exciting third-party risks! RENT could fold and Havelock could fold, leaving you sad and unhedged

By the same token MPEX could fold, I really don't see your point unless there is some cloud of magic surrounding the few listings on MPEX which prevents them ever going wrong.
The unusual thing about RentalStarter is it is a listing based on the ownership and rental of physical property which will retain value (as defined in USD). The issuer has been very open about the project and a creditable history in the industry making it hard for him to cut and run without being chased by litigants. You don't normally throw away a reputation build up over many years lightly.
This listing uses BTC as a method of transferring value, buying BTC for USD and distributing it out as payments each month. This is what BTC is good at as there are no bank charges involved.
Yes, exchanges collapse, BitFunder is a good example but the listings simply moved to another.
Regarding the price of RentalStarter, the volume is very low at the moment as people flock to the next high risk mining share for huge payouts, RentalStarter is paying reasonable returns for a bricks and mortar business in the startup phase. I am however surprised at the low share valuation at the moment which is significantly below the breakup value of the business which makes it a good and relatively secure investment in the hybrid BTC/USD world.
We disagree, you are entitled to your view, however childish insults don't help and just lower your reputation.
