I'll look into mining-dutch.

I've kind of changed my opinion on zpool due to this quote from their site:

"If a coin is NOT listed on the pool (except BTC) and you still choose to mine with that address, you risk not getting any payments. BTC is the only guaranteed payout currency"

From what I can tell if you select a payout that no one else on the pool wants to mine then you may never get paid. It seems that they will not use an exchange to autotrade your coins the way mining pool hub does.

Instead, I think that on zpool they only send out coins that others on the pool have directly mined. This saves on exchange fees but makes it so you have have extremely delayed payments. You might never get paid if your payout coin falls out of favor from the mining algos.

This means that if you do a mining test, zpool will have a very long tail where it's paying out your credits for several days after you stop mining. Because the coins vary so much in exchange rate this makes it hard to tell what value you actually got from it.

I strongly prefer that mining pool hub will actually exchange to your payout to get your withdrawals faster. There is still a delay but you don't have to manually fiddle to see if your payout coin is not being mined and have to update your miners all the time like you have to with zpool.
