Says they are up now.

I got one of their emails too. They must have bought a mailing list from one of the various coin forums or exchanges.

It seems reasonable to provide a receipt in USD or Euros based on third party conversion rates (bitstamp, Coinbase, etc). I don't know if this could cause any legal liability issues on the seller side of course (since the paperwork then looks like they accepted fiat payments for any internal audits on their end).

A work around might be to use the US based bitmain distributor, or wasn't there a UK one as well? Maybe one of those could provide you the invoice you need.

If you want to let organofcorti do the work for you, he has a weekly report such as this one:

If you go down to Figure 5, you can see his plot of recent Eligius luck.

Personally I find a primary reason to use p2pool is the freshly minted coins, and (while running your own node) protection from any sort of theft (either by a pool op or a hacker attacking the pool). Yes a public node could be open to operator abuse like any normal pool, so that'd be a wash. But a public p2pool is still mining coins directly to your own wallet instead of a central source for payment later (and a hacker target). Eligius does direct payment sometimes (they have had a lot of 'failsafe' mode lately, meaning they centralize the funds after all), but very few other pools do. A hacker also recently stole a good amount of NMC from Eligius as well.

It would be better to remove the Luck % column completely and show a CDF % column instead.

Could try Twitter.

Says they are investigating a security issue. That's a shame, I like their quick and easy to use web site and the various mining pools and auto-switch pools are cool as well since you don't need to run wallets for each coin.

You'd be buying 200GH of hash power in the cex.io exchange for 2.6BTC. As opposed to, say, buying a 180GH AntMiner S1 for under 1 BTC. At least .013 is better than the .04 people used to sell hash power for there, but it still makes no sense to me at all.

The 0.04194304  is just the default. You can lower it further to the minimum.

You are right, but the reverse is also true. Good luck now rewards you more than the bad luck later will cost you after a diff change. You can't know in advance if you'll have good or bad luck, and the odds of either are the same.

Primecoin is the only one I know of.

Is it time to remove "CPU-Only" from the thread topic?

I run a p2pool node over at http://us-east.royalminingco.com:9655/static/ so you could try connecting to that domain name and see if it gets you into the network. The port for the coin daemon should be open.

lightfoot, the problem of withholding blocks is that if someone else finds a block before you submit it to the network, yours can get orphaned and then you are left with nothing. Risking 25 BTC to try and get a 'head start' on another block wouldn't seem to make sense. And it's all random anyway, partial work means nothing. Your odds of finding a 2nd block are the same whether you report the prior block or hold on to it. I think all you do is hurt yourself.

Switch to Electrum.

Claiming they "don't exist" is a bit of a stretch. Bitmain has a track record of not announcing products until they are very close to shipping. They don't do 6 month in advance pre-orders like other companies.

You have to calculate the efficiency of the power supply. If at near max load it is, for example, 90% efficient, then a 1000W draw at the wall means about a 900W pull from the power supply by the hardware.

The rating for a PSU is normally the max power you can draw from it to your hardware, not the max it will pull from the wall. That will be higher based on efficiency of the PSU itself. A 50% efficient really old 300W power supply might pull 600W from the wall to run your 300W of hardware.

So roughly the power of 5-6 S1s.

Yeah Avalon shipped without PSUs because of all of the delays and complexities that would sometimes cause.

What's the appeal of merge mining coins other than Namecoin which have almost no resale value at all?
