This never happens in practice.
It's because their payout is higher than the actual expectation once you consider orphans.

Okay yes that makes sense. As soon as you get a single orphan (the expectation of) those shares will stay in the log forever.

Thank you for the explanation.


13842  Other / Beginners & Help / Re: Serious qestions about CEX.io and other cloud mining services on: January 08, 2014, 05:45:53 AM
Ok I've been running some thoughts and numbers in my head about CEX. Right now it is .04189 a GH so 1 Bitcoin would get you about 23 GH's. I have about $14,000 in a couple stocks right now that I am thinking about cashing out and buying bitcoins at the current price of $850 I could get about 16 Bitcoins. Now if I bout GH's with those 16 bitcoins I would have 368 Gh's (not including my BFL 60), at the next predicted difficulty level of 1,549,680,471 I would earn .1194 BTC per day according to bitcoinx.com. So if I did this for 30 days I would earn 3.582 bitcoins but with difficulty increase probably 3 bitcoins in a month.  Then I sell my Gh's hopefully for what I paid for them or more I could make a profit here I think, and then put my money back into stocks. My goal is to just get about 5 bitcoins total and then store them on a flash drive and CD for the next 10 years and then come back and look at them.

Any thoughts if this could work? Huh
Thanks.



Is cex.io legal?

Never really occurred to me to ask but they are uk based I believe, stringent financial regs. Since they don't take money money I am not sure what the status would be. Technically they are running an exchange (buying selling hash power basically the same as trading electricity in the eyes of a bleary bureaucrat).

I would have concerns about that putting a big chunk in and keeping it for months. Risk not worth a few extra coins considering opportunity loss if they grabbed your stash.

Just something to think about, like I said I don't know.


I see no advantage whatsoever (and significant disadvantages) if the plan is to buy and hold (mine).  Just buy some mining gear (which will likely be cheaper).  Why introduce a middleman who might implode, might be a scam, etc.?

If you are going to trade I could possibly see the merit, but not for mining.

What are people using to track their bots' progress?

Its pretty hard to do this in a meaningful way if you are running a balancer. If you do some simulations you see that results can be all over the place just due to luck.

You can draw pretty pictures of course, but if you are drawing conclusions from results over a reasonable time scale you are probably fooling yourself.

I first tried eligius, but it sucks
Don't like the concept of a payment queue, where they get to keep my btc for 6 days till they pay me
So I switched to slushs pool
Much better,and because you can login, you can see more accurately what each worker is doing
I have a separate worker setup for each antminer so I can see if there are any problems
I'm about 0.13 bitcoins a day
Which is right about where I should be Smiley

Eligius doesn't keep your coins for 6 days and you can login.  I have it set to pay to my blockchain.info wallet daily.  You just need to go into the settings and configure your payout limit.  Eligius has been pretty good in my experience.

Also, Eligius supports workers too. Just add _workername to the username (payout address) for each worker.

But nothing wrong with slush's pool either. I've used that at times and I'm using that as my primary backup now.

  • If the entire database was paid and there are still funds left, include it in the next block's reward

This never happens in practice. The database has shares that are months or maybe years old. It is not clear to me why this is other than bad luck early on by the pool (which would build up a backlog of shares in the database). Or maybe it is because p2pool apparently outperforms the centralized pools, so they will always have a bit more than their share of "bad luck."

Quote
I mine on Eligius and every once in a while I get regular payments (i.e., not "mined"/generated payouts) to my address so I just assume it was from coins the pool had to pay to itself due to a lucky streak. (or nice people donating/miners typing their address incorrectly :p )

I have no idea what those are. I don't think I've received them (but not positive, I've had payments going to several different wallets/addresses over the years so I may not have noticed). Maybe the operator correcting for some malfunctions?



13846  Bitcoin / Pools / Re: [117 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: January 06, 2014, 05:55:13 PM
Rules has been changed in last Bitcoin version 0.8.6. Maximum free transaction size is now 3 KB not 10 KB.
Also, all outputs of 0.01 BTC rule also have been removed.

That being the case all you need to do is collect up as many outputs as you can fit into each 3K transaction (roughly 10 I think) and send them to a new output. Of course this assumes enough of the network has upgraded to 0.8.6, which may or may not be true.
13847  Bitcoin / Pools / Re: [117 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: January 06, 2014, 06:36:44 AM
He means when you spend them later.  The payments to you are indeed generation transactions and have no fees.  Current payout for a single active share is something like 0.0045 BTC.  A spend of 1 BTC using them will be like 50kb or something, and will need some fees.

You can avoid these under the current rules if you a really really careful about how you construct the transactions, or at least minimize them given slightly less care. The bitcoin wiki has some examples. The standard client probably won't construct the transactions the right way though.

EDIT: I thought it had examples, but now I can't find the page. The gist of it is that you need to keep the transactions under 10kb and make sure that all outputs are >0.01. In practice this means not having a change output and it might mean having one large input along with the small ones you are aggregating. It might take multiple transactions but as long as each is under 10kb, you're fine. You might then need a fee to spend the entire amount because the outputs of the initial transactions aren't "mature" but the fee will be a reasonable percentage.

Maybe there's another thread somewhere for this but has anyone discussed that even with so much power of our Antminer S1, it's looking very doubtful that we're gonna get our ROI of 3.15BTC?  [I'm not complaining at all; as I suspected it from the start before I bought it  Smiley ]

You (meaning anyone, not just you) can not accurately predict ROI since it depends on future difficulty changes, and also on the residual value of the miner. All you can do on these is guess. If you guess that these will be low+high you should buy the miner, if not you shouldn't.

There is this fallacy that you can make a few clicks a on web site like genesis block, etc. and get a definitive yes or no answer on whether to purchase a miner. False.

As for mining some other coin if you look at profitability of mining other SHA256 coins it has generally not been favorable. Mining scrypt coins has been somewhat favorable. But as for the future, again all you can do is guess.

13849  Bitcoin / Pools / Re: [117 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool on: January 06, 2014, 01:26:13 AM
I don't think decentralized CPPSRBP is currently possible because there'd have to be some way to manage a pool wallet for when there's a surplus from a block reward/pay from it when needed and doing this in a decentralized manner would be very difficult.

There is no wallet or surplus with CPPSRBP. The Eligius coinbases pay out to miners, not a pool wallet.  There is a share log and every block that gets paid out to the most recent shares adding up to the value of the block. If the round was unlucky then not all shares from that round will be paid. If the round was lucky then some old shares will be paid.  I don't know enough about the internals of p2pool to know whether this is possible.

EDIT: This isn't quite right since Eligius doesn't pay out until your balance reaches the minimum payout. Still the blocks rewards are paid directly to miners (who have accumulated a large enough balance to get paid out), not to a pool wallet.

Been using middlecoin.com with some GPUs a while ago, he does some amazing trading

At a given point 3 GPUs worth 300 EUR (+- 1.2MH/s) were outperforming 50 GH/s of BTC Asics costing me *a lot* more

This is why I suggested moving the existing GPUs to a switching pool. Profitability has been running 50-100% higher than mining LTC directly for a while now.

13851  Alternate cryptocurrencies / Altcoin Discussion / Re: Ripple is not a scam - and you may be making yourself vulnerable to actual scams on: January 04, 2014, 08:42:18 AM
Anyone who can understand Bitcoin and doesn't understand Ripple isn't really trying. Could be lack of interest, lack of time, could be denial or massive cognitive dissonance, could be dishonesty.

You're absolutely wrong, in general. I read the Bitcoin paper a few years ago and I largely understood it. I read what I could find about Ripple a year or so ago, and I didn't really understand it, at least not in a big picture "How will I use this?" and "How does this entire system work?" sense. Granted I understand Bitcoin much better now than I did after reading the paper, but in terms of relative level of understanding after reading through what I was provided by the designer, it was simply night and day. That is a fact.

There was no particular difference between the two in terms of relative lack of interest, lack of time,  denial, or massive cognitive dissonance, nor am I being dishonest.

EDIT: I will clarify this a bit. I believe that I could possibly understand Ripple if I put in the effort to study it and work through the details. The problem is that I have no particular reason do to so. Giving me a few thousand free Ripples isn't enough incentive for me to care about this one out of many apparently-similar competing solutions. The difference with Bitcoin was: a) it was clear that it did something fundamentally new (as opposed to one-of-many or arguably-better), and b) I didn't need to put in that effort, because it was just easier to understand.
13852  Alternate cryptocurrencies / Altcoin Discussion / Re: Ripple is not a scam - and you may be making yourself vulnerable to actual scams on: January 04, 2014, 04:12:54 AM
Ripple is misunderstood because no one can understand it.

It will take time. Much like Bitcoin itself, it moves in a radical new direction.

No, that's the huge difference people are explaining, and you keep ignoring. It does not "take time" for someone to understand Bitcoin to a reasonable extent. Someone with a basic understanding of cryptography and computers can read the original Bitcoin paper from five years ago (as I did 3 years ago) and understand it pretty well. There is no such 8-page Ripple paper.


13853  Other / Beginners & Help / Re: Review of my experience with Coinbase.com on: January 04, 2014, 03:52:39 AM
I would like to know people's experience with selling BTC at coinbase.  I have my first big power bill coming soon and don't want to have any issues selling a few hundred dollars worth of BTC.  Are there delays and will they keep the quoted sell price even if the transaction happens at a later time?  

I have done a few sells all but one went through to my bank account on the exact day they promised. The other one was inexplicably canceled and the BTC put back into my account, but I can't complain because the price at that point was higher than when I sold.

But in the future, you never know. I would not count on perfect execution to pay your power bill. Start the process with some extra time and make contingency plans "just in case."

GODDAM IT.

This is the THIRD time UPS has shafted me (every antminer ive ordered). Just like the last 2 times, I was home all day for the package and left a note in the lobby with a buzzer code and instructions to come to the 4th floor.

Just like before, its past 7pm (its actually 9:45PM today) before the tracking status changes from 'on truck for delivery' to 'first attempt made'. Its too late to schedule a will-call with UPS.

What can I do about this? Its obviously not Bitmain's fault, but im seriously pissed off that once again the UPS delivery truck decided to skip me and mark me as 'attempt made' when no such thing took place. UPS call center of course gives less than half of a f**k.
Gotta complain to UPS, odds are the driver didn't want to go up to the 4th floor.

Yes complain to UPS, but track down a corporate number, not the call center.

What pool? nasty pool it's a simple p2pool node. I have one too, look: http://lenny.dnsd.me:9332/ Should I call myself pool operator?

You could, although that carries some commitment to at least keep the node up all the time. If it is just your own personal node you don't need to do that.

multipool.us is doing custom work - it enables small miners to have payouts again.

Also, multipool's BTC pool has 0% fee.
News from website:
Quote
Jan 01 7:36 PM PPC, TRC, FRC and ZET pool fees are now back at 1.5%.  BTC will remain at 0%.  NMC merged mining coming soon!

Okay that is good news. Always nice to have more options, especially those supporting p2pool.

I don't really understand MMC2, can't you melt 10 PTS to make 1 MMC2?

No, if you own PTS as of a certain block you get MMC2 as a one-time spin off. There is no conversion.

Indeed, multipool is mining on p2pool. They have 0% fee, and planning to implement merged mining.

Multipool is no longer 0% fee:

Quote
A: Effective September 1, 2013, this site charges a 1.5% fee on all mined blocks. Through January 1, 2014, all SHA-256 pools are 0% fee.

NASTY POOL has a p2pool with 0% fee. Merged mining supports the pool.  No fancy web site though, just the basic p2pool graphs.
