mpex.co  - yep I could just go there. Who are they? How long will they exist? why
should I line their pockets? Its a brush off answer on the replier's part, but
the fact remains. Using mpex.co requires I trust them. I'd rather not go down
that road as the BTC is not about trusting some institution.

bitcoin has no stable purchasing power. What item to peg its value to?
Of course, you are right, everything tangible fluctuates in value so
clearly Bitcoin cannot be pegged to anything.

By implementing an ability, within the wallet, to buy or sell BTC, current or on
a forward basis, the BTC system could collect very small fees, far far lower
than the fees charged by the exchanges, and hold these fees, in BTC, as reserves,
in the system, in a decentralized manner.

then, BTC has backing. that leads to stability of value. Without backing BTC will
fluctuate wildly every time a reasonable rumor surfaces. As long as that is the
case, BTC will not attract material (e.g.. $Trillions) investment.

the problem remains until we all admit its there and develop a solution.

i'd like to see BTC become a global currency, or even just distributed on 5 billion cell phones, each with
$50 of BTC in them for small payment opportunities. But, lets face it, if 7-11 accepts bit coins you can
be sure they've been sold and converted to real currency before you've walked out the door with your
bottle of water or soda. That is the problem. BTC has no stable purchasing power. No one wants to hold
it. Perhaps this will just change in the future? That's wishful thinking to me.
