Hi so far I have been mining single coins. Zen, xzc and others.
I understand I can use a site like mining pool hub to automatically switch to the most profitable coin. What's your opinion on this? Is it recommended?
Auto switch really nice if you use auto exchange pool. If mining single coin, most profitable coin is the coin has worst profitable. Because of this, that coin will have lower diff and you will get more coin. And then when the spikes come, just sell it
