It actually is pretty good right now. Those of us who made profit at 230... a bump like 270 even is a nice little bump for us. So the trick is being able to handle low priced mining times.
And the good news is all of the BTC you mined and did not use to pay electricity for example has today's value so your holdings can go up a decent amount as far as USD in just a few weeks.
So you are saying that you turn your mining equipment to half capacity when price is low, and full capacity when price is high? Thats a good strategy.
Or, mine always for maximum capacity, but only dump the coins at high price? This is riskier.
The problem is that difficulty is going up, electricity cost going up, and you need new mining equipment that doesnt ROI for months, to keep up the capacity.
It is though, but doable.
Better always mine full speed, you might end up losing more from not mining than from mining more efficiently. Of course its understandable if you need to pay electricity bill from your BTC earning, but if thats the case, your electricity rate is probably too high to be mining anyways.
At least thats how i see it for home miners.
The problem with this is that some miners under clock nicely. I have normal electricity nothing special. And I do pay for electricity so if under clocking brings me more money, I do it. For example my Avalon 4.1, SP20's are all running under clock as they do it very well and I can run at most efficient electricity.
Running full speed sounds nice but unless free electricity for most it will not work.
Or you can plan for later dumping, I mean at next halving the price can go to 5000$. Imagine how big ROI that would be.
Bitcoin can go to the moon, this is also need to be considered by miners.
It's getting a little away from cloud mining, but I guess some of these ideas do kinda crossover.
I have a set amount I want to be invested in. I don't believe in going deeper and deeper in debt in chance of ROI. I either make ROI or I don't. And hopefully there is ROI/Profit on my investments. If you wait on X price (which I admit I have done if price is horrible but as a general rule don't like). If I did this I would have been KILLED from day's of when BTC was worth double or more then it is today.
Going through something like when btc went from thousand or so to a ton less luckily did not kill me as I had ROI'ed on my holdings. If I held saying Ohhh if i get X more to pay the costs I do better, the drop like that would have crushed my investment. I think you had to go through this to see how things can go wrong.
