TBH, chasing short term profit mining only works with NiceHash. They make a log of your profit at a given time and add it to your balance. It doesn't matter if the price drops later, the coins you mined at a certain price get immediately converted at that exchange rate and added to your balance. In sites like MiningPoolHub you are actually earning coins. MPH only automates the exchange process and they have minimums for this, so it's very likely that the price will be different by the time of exchange than the at time you mined the coin. I'm not really sure but I think zpool is like NiceHash too.
So, for those mining coins directly, it's better to stick to one coin that have a good profitable average in a week.
I get that FOMO when using Nicehash, because in AM, the daily rate it shows is usually much lower than the "profit" that MPH or Zpool show. I'll mine at NH for a few hours then ask myself why am I mining at such a lower rate than what I was getting at MPH for instance. Then I wonder, why am I even bothering chasing coins, and go back to mining my favorite single coins and turn off profit switching.
I want to like NH, but it's got big fees, you only get paid what the buyers "market" will pay out, and just doesn't seem as profitable as the others. I think there is a thread here, where someone put 3 equal rigs on NH, MPH, and ZPool for seven days and surprisingly ZPool came out ahead. I was always hesitant to use ZPool because it's had some bad reviews in the past of them "stealing" large percentages of hashrates, intentionally switching your rigs to less profitable algos because they need to level out others and more.
I think I'll give Zpool a go through AM for 24 hours and see what happens.
