Mostly a novelty device for #Bitcoin enthusiasts. Mine is a cool little desk ornament that can be a great little conversation starter. There is some educational value there, as well.

If you point it at a pool you'll be maybe earning 50-80 sats a day, depending on the model you went with. It will take you years and years to accumulate enough sats to ever get a payout from the pool unless you mine with nostr:npub1qtvl2em0llpnnllffhat8zltugwwz97x79gfmxfz4qk52n6zpk3qq87dze or Braiins pools, which have payouts via Lightning. If you solo mine it's basically just sitting there making noise for the next 8,000 years, likely not finding a single block. But you COULD get exceptionally lucky and get a full block reward. Think of it like buying a lottery ticket with your electricity every 10 minutes or so.
