Yup, I'm also experiencing discrepancies with my actual shares generated and the shares being reflected in the pool.

I worked on the last block (the one found on July 10) for more than a day and throughout that period the stats were showing that I had an estimated reward from that block of around .35BTC.

But now the stats are telling me that I contributed 0 shares to the discovery of that block and so I don't get anything 

I have a 5870 and a 6990 together under Windows 7 32 bit. The 5870 is the primary board attached to the monitor with the 6990 dummy plugged. (This isn't a dedicated miner so I wanted the 5870 to take the performance hit whenever other programs needed the graphics card.)

Whenever I try to install drivers (Catalyst 11.6) they install without any problems but I noticed that in Afterburner no driver information is displayed for the 6990 GPUs while when I shift the settings to the 5870 the driver version shows up correctly.

Does that mean the drivers aren't "reaching" the 6990 when they install? 

I'm asking because I'm only getting around 350mh/s per GPU on the 6990 and have been trying to get them up to the 432mh/s or higher (as discussed here: http://forum.bitcoin.org/index.php?topic=25798.0;topicseen) without any luck. I've tried using Phoenix 1.50 with all the recommended flags and still the hash rate won't go up.

So I'm thinking its the drivers?

Any help is appreciated!

@MadSweeney: Thanks for the inquiry but right now I'll have to stay with the posted prices. Di ko kase mapredict yung presyo ng BTC, biglang tataas, biglang bababa. So I tried to keep the posted prices within a level of reason keeping that in mind. (Baka padala ako ng padala ng load tapos biglang babagsak pala yung presyo. Kawawa naman CP bill ko )

Nice to know there are some pinoy miners!

Good suggestion, thanks!

This post is only relevant to those in the Philippines. If anyone wants to exchange BTC for Globe/Smart/Talk and Text/Touch Mobile load, please see this site for more information:

If you're curious, yes, I live in the Philippines, am Filipino through and through and the above is my small contribution to jump starting BTC trade in the country

Obviously a noob question. I thought difficulty was constant between rounds.

However I found a difficulty estimate here: http://dot-bit.org/tools/nextDifficulty.php which has estimates for the last round, the next round, and the "instant" blocks currently being processed. It's this instant part that's confusing me as its difficulty fluctuates.

Thanks for enlightening me!

So suggest your own way of attempting to determine which way BTC value will go 

It would be interesting to see that data on the volume of BTC transactions and how it relates to changes in BTC value. I guess the assumption there is that the more BTC is used in the real world (ie. that it can be exchanged for goods and services just like any other currency) the higher its price will go up. That leaves me wondering though if BTC price right now is simply determined by the movements of speculators...


Maybe I'll post the topic again when I'm out of the ghetto of the newbie section 

Good to know, thanks!

Was wondering what exchanges you use and which you would recommend? I use bitmarket.eu, and am quite happy with it, but am always open to exploring alternatives.

Was curious if anyone had any observations on "real world" events which affect BTC price.

For example, for real/sovereign/fiat currencies usually a rise in inflation decreases the value of that currency. External shocks, such as natural disasters, change in government, etc. also move currency price up or down.

So has anyone observed any correlation between real world events and BTC price?

As has been noted in other posts, difficulty does not in itself affect price. (Ok, before you flame me... Certainly difficulty may contribute to determining BTC price but it doesn't seem to be a strong enough factor by itself to significantly affect the price.) This is evidenced by the dramatic increase in difficulty in the last round without a corresponding dramatic increase in BTC price.

I noticed that in the days after Greece passed its austerity measures the price of BTC has dropped somewhat. To generalize rather broadly, perhaps the health of marquee real/sovereign/fiat currencies (USD and the Euro) is inversely proportional to the price of BTC.

I'm asking because I'm not satisfied with the explanation that BTC price goes up or down simply depending on when old miners who have been hoarding their stashes suddenly decide to cash in their chips
