After carefully reading the OP I've decided to take a much closer look at Monero for potential investment.

Now THIS is WAY more bullish than any Mintpal addition.  Of course you don't really LIKE the idea of Monero do you Jorge? 

Is it bad to keep our money where there is no way for government to see?

I am very very worried about what my government thinks of it.  Which is one reason I am glad there are ways emerging to protect my financial privacy.

btw - while I haven't been annoyed enough about this gpu-fear-hype machine to actually hack stratum/jsonrpc code into convoluted c in cpuminer, I have been annoyed enough to spend a bunch of time optimizing the CPU miner, and Zoidberg has done the same.  The most recent commits improve standalone CPU mining speed by somewhere around 20% on windows and 57% on Linux:

(lnx):  https://bt.irlbtc.com/view/577267.msg7452285#msg7452285

We won't know how the increasing scratchpad size, optimizations, etc., all interact, but I believe that these improvements will narrow the gap substantially between the hypothetical GPU miner, any private optimized miners hanging out there in secret, and the every-day small-scale pool miner.  I'm even optimistic that these changes are better for desktops than for massive EC2 servers, which is kind of fun.  Archit tells me he's making progress pursuing the cpuminer stratum/bbr integration bounty.

So with all of this, I hope we can put the mining distribution FUD to sleep for a while.   Call me weird, but I think the most important battle is not between XMR and BBR.  Both are at the forefront of privacy-enhanced cryptocurrency, and some push and shove between them as they claw for market share will probably be good for overall innovation in the cryptonote space.  The real question will be real-world deployment and use vs the bitcoin family:  how much does the market value stronger anonymity and privacy, and to what degree can these features be successfully backported into existing currencies?

i seriously doubt there is any meaningful correlation between bbr and xmr pricing, once you subtract beta factors.  that doesn't mean bbr isn't dilutive -- it is dilutive, but only in the short-run.  (in the long run dark liquidity will be a monopoly, i.e. radically dominated by one vehicle.)

bbr is a one-man show run by a very talented control-freak.  in order to have any hope of becoming the monopoly currency it would first need a complete relaunch under a new name, with a competent CEO type at the helm, and a diverse development team.  

that said, it has interest, it is making a contribution, and it will probably do well, as minor alt currencies go, if only on the strength of CZs talent and energy.  as it is open source, we all benefit from those contributions.  while it is understandable that one might prefer not to be diluted in the near term, that is just a necessary cost of benefiting from those contributions.

In contrast, QCN, MCN, FCN - these are just crap.  If I were the judge, the developers of these coins would be shot and their families billed for the bullet.  The BCN founders would merely be sent to Fort Leavenworth for a decade or so.

such butthurt, much anger

So, 0.0067 at diff 641mm,
0.0104 at diff 775mm
So, estimated cost to produce = Difficulty/82800000000
Difficulty at 1 billion (how soon?), then cost to produce=  0.012 ?

One had might as well do it right.  There are other variables, although they vary less rapidly over time than does difficulty:

(Difficulty hash/block * Rate $/hr) (Hostrate hash/sec * 3600 sec/hr * Reward xmr/block * Nonorphan block/block * Exchange $/btc) = N btc/xmr

Rate (EC2 c3.8xlarge spot instance pricing) is ~0.2575 usd/hr [1]
Exchange is ~600 usd/btc
Difficulty is 8.1e8 [2]
Hostrate (EC2 c3.8xlarge) is 610 hash/sec [2]
Reward is ~16.07 xmr/block [3]
Nonorphan rate (pool mined) is ~0.93

EDIT: with new parameters at this moment the marginal production cost estimate is 0.011 btc/xmr (2014-06-23 01:00 GMT)

According to Wolf, his miner gets at least 1.2kH/s on an Amazon EC2 instance (didn't say which one but lets assume its EC2 c3.8xlarge)

"I ran a test, LucasJones' repo against mine. Each had the exact same CFLAGS (-Ofast -flto -fuse-linker-plugin -funroll-loops -fsplit-ivs-in-unroller -fvariable-expansion-in-unroller -falign-loops=16 -falign-functions=16 -falign-jumps=16 -falign-labels=16). Each were run with 21 threads for a period of time over 20min. I can't be more accurate than that, because I didn't sit and time it. They were run at seperate times on the same machine - a 32 core Amazon EC2 instance with 58GB of RAM. The results? Lucas' cpuminer reported 627.58H/s - but only pulled 600 at the pool. My miner reported 1021.73 and pulled an impressive 1.25KH/s at the pool. Now, even with vardiff causing high share difficulties and luck contributing to inaccuracy, this shows a clear 100% increase. I have screenshots to prove it, but before I post them, I have to warn - I was too lazy to crop out my wallpapers, so they are NSFW."

Using wolf's hash rate and current parameters, I get marginal cost of 0.00653, which corresponds more closely to current market clearing at 0.007
