I don't even know which alts I would consider worth investing in these days. Many of them need a miracle to go up a lot and I am just tired of believing in miracles.

This is true, however still there are very attractive ones to mine, as I see from my own perspective
how attractive the coin will depend on how much hashrate that you can get if you are having a little hash rate power and you will always get the lose only because what you must be paid will be deficit compared with what will you get from your mining rig.
