Nicehash is good when altcoin prices are going down (in my opinion). So you don't lose 10% between mining the coin, and selling it on the exchange. Even if you do it automatically you lose. So yeah, nicehash is good. Also good when there are new big coins. Maybe Phil you can put one rig on Sniffdogminer or nemos, just select a few algos like bitcore, phi, hsr, skein, phi, xevan, neoscrypt for example. Profitability seems to be a bit higher on average, and if you do it on zpool, then its the same deal as nicehash - paid in btc - although I dont really like zpool that much.
I am on my secondary account. A great switching program will earn more than the way I mine but I sell off my gear..
And I run it on 70% trip not to stress the gear. So switching will be harder on the gear. Anyone that got gear from me knows it works well I do not want to risk gears health with switching software. I actually earn more with sales then mining. Philipma1957
