Stop mining and it will drop a bit.

Hem sorry, what is -q and -E ? it's not listed in help and doesn't seems to work
Queue and expiry-time, thought the cpuminer had those options too but not sure, I remember these settings from countless scrypt orphan orgies. Most important to avoid orphans is the -s aka --scantime setting though (the amount of time between checking for new blocks).That's great, many thanks.

Most important to avoid orphans is the -s aka --scantime setting though (the amount of time between checking for new blocks). If you got many orphans that's probably because you solo mined with the cpu miner but used the standard scantime, which is 30 seconds. I recommend adding -s 1 -q 0 -E 2 to the commandline when solomining with the cpuminer.

about how many blocks can i expect per day at 160k Hashes per sec?
Maybe once every couple days...
thats crazy bad profitability :/
At time of writing, the Quarkcoin difficulty is 441.12747160.
The formula for seconds per block is 2^24*
2^24 * 441.12747160 / 160000 = ~46,256 seconds per block
46,256 / 60 = ~771 minutes per block
771 / 60 = ~13 hours per block.
There's the maths for you.
FWIW, here's what it would take me, mining at roughly 605kH/s:
2^24 * 441.12747160 / 605000 = ~12,233 seconds per block
12,333 / 60 = ~206 minutes per block
206 / 60 = ~3 hours per block.
That's a 4.3x decrease in time, for a 3.8x increase in power. There are small economies of scale.

Thx for the calculation but what about the orphan rate ?
Most of block found are orphan, how do you determine the % orphan rate ?
post your quarkcoin.conf then
@quarkcoin @Guido
That looks amazing!
I'm holding some qrk...usd worth is similar, that's true.
I expect block reward halving to increase price over time.

The price for QRK isn't really falling. Look instead at the BTC/USD trade rate over the past week. There's the answer. BTC up >40 %.

How much coins is in block now? 1024 or 512?
Has now halved to 512Jump to:
