Like you said, it's less of a headache to do it manually. I did used Multipoolminer & tried to get some other auto-switcher to work (forget which one) but I don't think it's worth it.
One reason I think these auto-switcher may fall down on is that they may detect a "wrong" best coin and end up mining it before you notice.
Look at the screenshots below from Mining Pool Hub, taken only a few minutes apart, why is Feathercoin suddenly the best coin to mine, then it's one of the worst to mine ?

I been noticing that myself, and its taking nearly a whole day when using the auto convert coins option, they take several hours to be sent to the exhange then they sit there for ages , and take ages to credit back.  I not had any problems with rejects tho but I dont touch ethereum as I have nividia cards and its futile

I don't understand how you hear of various retailers accepting Bitcoin when, and it's not the transaction time that's the main problem - think of credit card transaction they can, effectively, take 4 to 5 weeks to 'confirm', but the transaction fee; it could cost as much in transaction fees to buy a coffee as it would for the cost of the coffee itself !

Exactly man, i was reading some guy that said Bitcoin should never escalate, that he was able to send 100.000 USD for a very low fee... they want to make Bitcoin a long store of value for the rich instead of a usable currency for everyone...

mining is becoming harder everyday cause you have to wait hours and hours for your earnings to return to you...

I saw you are a Experienced Member here, maybe some advice why MiningPoolHub was rejecting 30% of my shares on the Ethereum Pool?? i was using Nicehash USA Servers so i really dont understand what happened, Pool Stats never show always 0, so ididnt notice my rejected shares till was too late.... not fun to loose money like this

Thanks!!

Any plan for adding VERIUM ( VRM ) into miningpoolhub ?

Hey MPH owner, your pool is great and all its features.
I would like to ask something (it might have been answered already):
At what price does the auto exchange happens - at the time of Debit_AE or at the time of the Credit to exchanged coin?
Thank you and keep up the good work!

And i have one question more.
My rig have 2280Sol/s hashrate. Pools hashrate is 28Msol/s.
So i should have about 2.28/28000=0.000814ZEC per round
but my last transactions:

14550057   2017-10-15 11:10:20 (UTC)   Credit   Confirmed         202217   0.00063184
why so low?

That's not how pools work; you don't get paid for your hashrate although it has a direct effect on your rewards.
You have to mine continuously for days for actual payouts to have any accuracy.

Yes i mine continuously on MPH for last days. And i just cant understand why my earnings per round so various (0.0005-0.001) although pools hashrate doesnt change so much (27-28Msol).
Amount of shares is propotional to hashrate anyway

An hour of payments has little meaning.

The pool is distributing what we find:
