I'm always on the lookout for ways to support small miners. It's the reason HeliosPool started. Sometimes that means looking for interesting/weird/meme coins that these miners can solo.
DGB is one of the more popular small diff coins, and it's been amazing to see those blocks roll in on the DGB pool, but its still in the high M to low G range.
Came across a coin called CheetahCoin. It was easy enough, as a fork of bitcoin, to adapt the software to support it. It's diffs range around 2.5M with momentary spikes to 20G, when blocks come too fast, to discourage ASICs.
2.5M is not something the esp32 miners will hit often, but it might be a good coin to experiment with.
It's tradable almost nowhere and it's value is practically nonexistent - so it's perfect for a little fun!

Let me know what you think. Any other coins I should be looking at?
