I am trying to avoid powering down but seen others use that strategy and it seems to be working. Yeah, there is a fine line between abusing and not abusing bots. Bot abuse / use can cause downvotes so there is that to consider also. I am not saying I use the strategy lined out, just that its possible.

I never did any exact calculations on how price fluctuations would effect the ROI. Crypto is so unpredictable Its almost pointless to do so. If the price takes a big swing do the calculations then and if something is no longer profitable adapt an change.
