Is mining with mobile device a profitable venture today? I read a bit about this and learned that Monero maybe worth mining. then there's Electroneum as well. I wanted to know from other's experience.
One might ask why spend on buying phones. Instead get a PC. Thing is I have few old phones that I can't sell, I want to see possibility of getting some cost back before giving/throwing them away
I think not, if upgraded computers are having a hard time mining the bitcoins then cellphone computers would not have a chance to mine them.
