So a lot of people have been throwing around the term 'variance' as a defense of why they want to mine at only the largest pool.

Does anyone have a method of calculating the variance, both over a day and over a bitcoin difficulty period (10-12 days) based on difficulty and hashrate?  I started looking around on some sites but the math is a bit over my head.

I think if we can show that variance is not really an issue when using a smaller pool (down to a certain threshold, anyway), people will be more likely to move away from giant pools like ghash.

Cointerra why are you not honoring your hashrate guarantee for Early January customers?

I emailed support and received this response:

Our legal team has determined that the 30 day late delivery agreement does not kick in until March 2nd. Sorry, I know that this is such a hassle.

I think everyone accepts that there were delays and you might be late delivering, but I'd imagine this guarantee caused a lot of people who would not have ordered in the first place to order your equipment.  Please explain how March 2nd can possibly work as a guarantee date for "Early January" orders.

I tried to ask the same question in your forums but my post was not "approved".

Multipool is offering the pool fee (1.5% - 0.3125 BTC) plus any transaction fees up to a total of 1 BTC for the person who finds our first block!

Multipool is in serious need of more hashpower to find our first block.  I'm announcing the following promotion:

The person who finds our first block will receive the pool fee (1.5% - 0.3125 BTC) plus any transaction fees in the block, up to a limit of 1BTC.

Do not deposit any digital currencies into PhenixEx.com.  They are currently not servicing BTC withdrawals and some deposits are not showing up either.  I myself have been waiting over 5 days for a BTC withdrawal and many others are in the same boat.

UPDATE: At this point I believe a scammer tag is warranted for the involved parties.  How do we go about requesting this?

If you bid on these, you are dumb.

Per the following post (https://forum.litecoin.net/index.php/topic,4002.0.html) on the litecoin forums, a few pools have reportedly been attacked by miners exploiting this vulnerability.

The vulnerability in the viperaus fork of stratum-mining (and possibly others) allows miners to submit extremely low difficulty shares that will be considered valid by the pool because the difficulty calculation is off by a factor of 2^16 (65536).

Thanks to Skyfall on the Litecoin forums for posting the patch:

Now that BTC is above $100, is it time to reconsider the amounts for Donator status?

I'd like to donate something, but I can't afford 10BTC for donator status.

Our first block bounty was claimed this morning, I'm offering an additional bounty of 5LTC per (non-orphan, valid) block to the miner who finds each of the next 10 blocks!

Update: One block remaining for the 5LTC bounty!

Congrats to Newtoke who found our first block!

I will be offering a bounty of 5LTC per block for the next 10 blocks found.
