I have seen a several apps claiming to do this, but I am not sure how legit or profitable they are. I really appreciate any honest insights or advice from you guys. Thanks in advance.
Even with that claim, you sure haven’t seen it all as, more would be developed and sent in different stores just to get people downloading and using while, consuming both their data, energy and time.
There was never a time when mobile devices were used to mine Bitcoin, the closest it got was with Desktop computers with GPUs can serve the purpose and that was from a long time ago, during the genesis stage of Bitcoin.
Now, it’s only sophisticated ASIC devices, Bitmain Antminers and more which are specially designed for the purpose and they aren’t cheap. We’ve come too far to mine using just mobile phones.
