I am not trying to make a bunch of money and I would be happy just paying for my hobby over a reasonable time frame. Thanks in advance for any help.
There are basically 2 ways one could approach the mining game — efficient and adventurous.
The efficient way is to mine whatever is most profitable at the moment, and then buy whatever it is you think is worth having. So, for example, let's say you think that monero is worth keeping in the long run. But with the current difficulties and exchange rates, mining some other coin is giving you more in terms of BTC value (let's say it's Alloy vs XMR). So you're mining Alloy then, and exchanging the coins you're getting to XMR: this way you're getting more XMR than you'd get by mining it directly with the same hardware.
The other approach, the adventurous one, is to mine coins that you can't buy anywhere. That's usually new coins that haven not been traded on any exchanges yet. This is a lot riskier since the coin doesn't have an actual market "value", but might also be more "fun" (and more profitable in the long run). So, try both approaches and see what makes more sense to you.
