I like SMPPS since it has the best of everything: low variance, easy auditing, minimal to zero fees, no problems with poolhoppers.  The only downside is your payouts are slightly delayed.

I left Eligius because I object to littering Christian prayers all over the block chain, but in every other regard they run a good shop.  Arsbitcoin is my new choice for a midsize SMPPS pool.

What about smaller pool like eligius.st? Seems like a steady payout regardless of block size. They outpaced BTCGuild and Bitclockers for me. Does Deepbit payout more than them?

also their size alone give them legitimacy, as it's less likely they will do anything shady behind the scenes.
It's far easier to hide that as "noise" though for them...

Try to prove that they don't take a block every week for themselves! Wink

Someone is sitting in the shade today...
Is there a reason for deepbit to be so popular despite it's being popular anyway?

I mean they charge the highest percentage and all these 'advantages' they offer like paying for invalid blocks is a statistical zero sum game...

simplicity and safety, i dont care if i earn a few bitcoins less each month as a tradeoff.  I log in their website once a while and see my coins automatically transferred to my wallet, all my miners running, and everything just works, website is easy to use and the whole exercise takes less than 30 sec, then i move on with my life.

they had some stability issues a month or two back which i complained loudly and almost switched pool, but since then no downtime or any problems so i stayed.

also their size alone give them legitimacy, as it's less likely they will do anything shady behind the scenes.

the only thing i wish deepbit will implement is an alarm that auto sends an email if your miners are down, as it is now i still have to log in once few days to check on my miners.

no
*if* they get over 50% or the network they have a "chance" of taking over the network (if they wanted to), but even at 90% of the network there is still a 10% a chance they would not succeed.
false, at 90% of the network if they hide the block chain they have 90% chance of generating one block, but the chance of generating two blocks before the main chain generates two blocks is GREATER than 90%

(...) If it is a concern for you mine on a mid sized pool and encourage your friends and acquaintances too Cheesy

Yes, that's right.

The first Brazilian pool is coming soon.  Wink

Jack of Diamonds,

Yeah.  rfcpool has closed the 7% PPS and has relaunched with a PPLNS system.  I previously mined Prop and PPS.  So far, I prefer PPLNS.

ABCPool ? I currently have 8 GHash on this pool, and it totally rocks. Pay per share with 0% fee.

noobs assume biggest = best, easier than researching Wink

I am a noob; but I don't assume biggest = best.

What's the alternative to deepbit? Let's examine this ..
2nd to deepbit is slush? I tried slush, I didn't like the fact that they don't have instant payout and their payout is at 0.01 denomination. Call it a deja vu effect but was totally unhappy with the experience I had with bitcoinpool.com and bitcoinplus.com

3rd in line is btcguild.com. I love that site until recently ... search btcguild.com and you'll find a thread about possible scam.

No. that's not how it works. It's not that simple. Please refrain yourself from posting wrong statements.

Just saying that you WILL loose money on any proportional pool to pool hoppers if you don't hop yourself.

If you don't want to hop, don't go prop!
(unless you feel charitable of course - in that case, happy mining!)
I'm yet looking for proof of statistical significance that pool hopping even makes a difference.
It seems to be based on the assumption that there is some measurable "pool luck". However, mathematically the chances of a certain hashrate  at a difficulty are always the same independently if the last 2 blocks where a month or 2 seconds apart.

No, it's based on the definition of Prop. that early shares are worth more than late shares. For more info look up the users Raulo and Meni Rosenfeld in this forum, Meni is working on a more thorough paper on this topic and Raulo published the initial findings already in February - including a mathematical proof.

Maybe a more real-world example helps:
Imagine some nice guys in vans just opposite a school (=pool operators) who give out various amounts of candy to kids (=miners) each day.
The kids that manage to be quick and be always first in line will "earn" more candy than other kids that are a bit more lazy and just check every now and then if the van of their choice is there and also end up in the end of a long queue while the quick kids either are already at other vans or trying to earn money for candy elsewhere.
These quick kids (that monitor several vans and run quickly to the next one arriving) will however be eyed suspiciously by other kids, as they earn more candy. Some even say that they "steal" candy from them, just by lining up in front of them each time. Also the risk of being screwed by one of these nice guys in a van (who rarely even have a license plate to be able to identify them on their website van) increases of course.

Now there is something else which could factor into the equation, namely corrupt pool operators keeping blocks for themselves. If that is the case pool hopping can certainly make a difference. And if it really does this is proof that lots of pool operators are doing this.

If any of your miners are on proportional, you'd better run a pool hopper! Tongue

Never! I will not stoop to fucking other miners out of what they should be getting.

Less variance.
Any PPS pool has the lowest possible variance... there's no need to be big!

Yes but when your miners are on Proportional (Not PPS) there is less variance at Deepbit because of the higher Hash rate.

True.. Size doesn't matter with PPS.
Until ~2 months ago nobody else had the balls to compete with deepbit though.

If I'm not mistaken, rfcpool.com was the first competitor with their 7% PPS scheme, though they switched to some other reward model.

Now we have btcpool24.com and abcpool.co which are 0% pure PPS, with optional donations.
