I don't get it. Why would you split? You choose the most profitable one and stick to it, until you find a more profitable coin, then you switch your entire mining power to it. Now, I remember during the time I was mining that the profitability of certain coins changed all the time, so I had to do a lot of switching but I never split my mining power. Maybe there are legitimate reasons to split but I never did so.
Depends on your situation, strategy, and cash flow I'd imagine. I can give you a few reasons I split my farm up.
1) I have several different rig configurations (RX rigs, Vega, GTX 60/70/80, etc), and they all perform a bit differently on different algos. So I try to keep them pointed where they perform the best/better, for the most part.
2) We dont take profits short term at all. Other than my time keeping everything running, we have zero overhead...and the time I spend on it I dont put a whole lot of value in. It's not that I dont value my time, I do...but it's mostly just time I would otherwise be spending playing video games or a round of golf or something, so it's a value add instead of a value negative. As such, our time horizon is medium to long term hold, so I'm not overly concerned about short term profitibility. Mainly we want our BTC/ETH bags to grow, and have zero time/desire to day/swing trade coins on exchanges. Essentially we are using hash power to dollar cost average in directly to a specific portfolio allocation. For the most part, we only use the coins to buy parts (build/upgrade rigs, replace dead fans/risers/etc).
3) Taking a few swings at newer algos when they first release, and the difficulty is low. Like I said in a previous post, we dont do a whole lot of this...mainly just let software auto switch on it's own. I'd guess, on average, about 20% of total hashing power spends about a week or so a month on something speculative. Now that I type this out and read what I'm saying, I probably need to do a better job of tracking this...
Anyway, I doubt what I'm doing is "right". I'm quite sure there are better ways to go about doing it....but considering the resources we have available, the professional & practical limitations we have as a group, and our longer term goal this is what is working. Currently. I reserve the right to change my mind.
Thank you very much for your elaborate answer. I see now it is a much different game when you have several different rigs. It makes more sense the way you do it, not chasing the daily swings and not engaging on the market every day. But then, as you said, you don't have too much room for speculations or experiments. You have to mine the more established coins, not worrying what will happen next week or next month (which you would have to worry about if you mined some new hot coin).
