The list is more than confusing since you wrote in a number of places ETH instead of RVN.
Then, as said, investing into mining just in the moment the market starts to rise is a bad business. Especially as the expected income is far from great and even you subtly suggest holding.
Why not buy and hold? The investment can be smaller than the one for hardware (the ones wanting to enter mining may not have more than maybe 1 GPU) and there's no stress about ROI.
