Besides switching being kinda the point of the pool, the pool is configured not to switch unless the profitability of the other currency exceeds the profitability of the coin being mined by 1%.  The pool will also stay on most coins for at least 10 minutes to prevent hopping too fast.  (exceptions are MNC, LKY and ARG.)

For example, if it just switched to coin A (profitability 2.0) and suddenly coin B gets profitability 10.0, will it still wait the full 10 minutes before switching?

Yes.  I may need to tweak this now that there are other coin switching services gaining popularity.

If we lose 0.5% efficiency over 10 minutes by switching coins, that's 3 wasted seconds. For example, we're currently mining coin A (profitability 2.0) and coin B reached profitability 2.02. Thus, coin B is 1 % more profitable than coin A and we'd have to mine coin B for at least 3 / 0.01 = 300 seconds to make up for the 3 seconds lost due to switching coins.

Therefore, I think that rather than observing how much time has been spent mining the current coin, the pool should estimate how much time it will spend mining the one it's switching to (which might be hard).

My point is, independently of how many time has been spent mining the current coin, switching to a coin with swift difficulty adjustments might not make sense if that coin is only 1 % more profitable than the current one, while switching to LTC/NVC/FTC almost always makes sense while it's the most profitable one.

Speaking of switching: Do you think it would be possible to switch coins without forcing a stratum disconnect? My (limited) knowledge about how the stratum protocol works suggests that all it takes to switch coins is announcing a new block and a new difficulty.

All good points.  I agree especially with your second point and I am continually improving the switching algorithm.

As far as switching without a stratum disconnect, I'm pretty sure it'd be possible, but you'd have to rewrite the stratum server to connect to all the different coin daemons, reinitialize work, etc.  I've done some thinking around it and I believe it'd be doable, but it's a fairly large project and would require someone with better Python skills than I.

On the other hand, if we wait too long to switch then my inbox would be flooded with emails "DGC is 5% more proftiable why aren't we mining it???!"

Maybe as a long term goal. It should make switching coins not much more expensive than switching blocks and those of us who have stability problems (CGMiner sometimes crashes on stratum disconnect on some computers) would benefit greatly from it.

I don't have a single doubt that this will be a side effect.

Is anyone else having trouble withdrawing MEC ?
When you click the cash out all I get is a page refresh, coins stay put.

Plz check it out

Wow, I noticed the wallet was getting a little low earlier, so I sent over 2000 coins.  Looks like those have been withdrawn already so I sent over another 4000.  You should be able to withdraw soon.

Thanks, that has resolved it!

BTW love your pool, and the work that you have put into it.  Have been with you for few months and I appreciate all the improvements you've made in terms of coin support and improved connectivity. 
Used to pool jump all day long, but its crazy how many scamming pools are out there...
Nowdays I use your pool pretty much exclusively apart for few drop outs you experience once in a while.
Keep up the good work and I'm going to up the donation %
Thx again

Something wrong with web site, i see "mining FTC" for a long time, it seems like site going down 3 hours ago.

[Vampire_sumy]

Also as for switching between coins, i think it would be nice switch only if profitability of new coin is higher for 4-5% then currently mining coin. This prevent us from often switching between coins with almost equal profit.

I've found that regardless of lost efficiency due to coin hopping on this pool, it's still more efficient than monitoring coinchoose/coinwarz every few hours and manually switching.

[clintar]

I've been using your pool for a little bit now, and it's a great idea. I've been concerned since I can't keep on top of it enough and lose profitability probably, so I give up (plus not having wallets for every coin bugs me), but what do people do to minimize that? Use APIs to auto-trade or something? Anything out there like that or should I just chill and let my meager hashing slowly raise up the random coins and cash out when they get profitable again and I hit one coin?

While prices rise and fall, and there is always a risk a coin's price can crash, most of the profitability fluctuation is due to mining difficulty and not prices.

Ah, that makes sense. So it's the actual mining at a good difficulty that matters. Eases my mind. Thanks. Probably could have figured that out if I read the thread a bit. Sorry about that.

Hi Flound

Does your todo list include looking into enhancements of the cash out process, e.g.:
- an intermediary step after clicking to cash out, i.e. "You selected to cash out XYZ, are you sure? (yes/no)"
- for cases where the hot wallet is low / empty - perhaps a pop-up message along the lines of "Apologies for the inconvenience, but the hot wallet is still awaiting confirmations for coin XYZ. Your cash out cannot be processed at this time. Higher powers have been informed and will get back to you.." and if there is an approximate estimation of time you can give for the confirmations, that always helps.. and if you can also add an option like "Would you like your cash out to be added to the queue for processing as soon as there is sufficient availability in the hot wallet [although it is advisable that you use the Auto Threshold option]? (Yes/No)"

Yes I do want to revamp the entire cash out/payment process, just haven't had time recently.

[flound1129]

The new account details page is now live.

Features:
- Per-worker user-selectable share difficulty!  (Currently in BETA, only works on pool2.us.multipool.in which is also in BETA.  If you want to test this, please set pool1.us as a backup and please report any issues)
- More concise display!
- More ads!
- Worker deletion should now be reliable and not delete the wrong worker.
- Active worker display with 1 minute and 10 minute hashrate for all workers that have submitted shares in the last 10 minutes.
- Current BTC value is displayed alongside account balance.

Hi Flound,

    I was thinking it would be nice to know current BTC value of items in your payments area under the account detail.  Kind of like the profit snapshot but instead using what is already been paid out and is sitting there not cashed out yet under payments area.   I don't know how difficult it would be to implement.  I don't cash out everything everyday and sometimes I wondering what all these non cashed out alt coins are worth currently.  If I only have one alt coin its easy to go check against the current price, but with lots of different alt coins it is not as easy.

Thanks

Good idea!  I've implemented this.

[paymetodostuff]

Flound, do you have any guidelines or suggestions as to what to set our share difficulty to based on our rigs hash rates?

Thanks!
