Home mining is still pretty fun even if it’s not very profitable anymore. For many people it’s more about learning and supporting the network.
Small ASICs like Bitaxe or the Avalon Nano series are nice because they’re quiet and don’t use much power, so they can run at home without much hassle.
If anyone wants to check estimated earnings for small miners, this site is helpful:
https://www.asicminervalue.com/Curious though, are most people here pool mining or trying solo mining with these small devices? Some people run them solo just for the chance of hitting a block.

I'm not rich enough to buy such expensive devices. I'd rather buy a cheap old ASIC s19 and try solo mining with it. I'll have a better chance of mining a block. But I'll have to spend a lot more on electricity.
I am thinking if it's possible to run the s19 on solar panels during the day, from morning till day break only, but what's the point of you can't run it through all day? A block won't tell if they plan to be solved in the day or night, this is why running all day is best.
Using solar panels for solo mining isn't really worth it if your hardware is taking high wattage, you won't want to run such on your backup even if your panels can handle it.
Smaller hardwares are best for solar mining, unless the person is very rich that they can spend thousands on better battery backup, it's going to cost alot.
