Personally, I've never had a satisfying experience mobile mining. So far, it's just been a great way to stress your phone for fractions of pennies over extended periods of time, during which your phone is unusable. I've tried on several devices and never saw a hashrate over 20/s, most older devices being between 5-10. Many Youtube videos can verify those speeds, although they vary by miner. Mobile mining is great for the novelty, but don't expect it to translate to actual monetary value without running a farm of donated devices using electricity and internet you're not paying for.

How does Phoneum differentiate itself from other mobile mining products?
