I have been thinking of mining with my phone for some times now, I have gone through various online resources on how to mine with smartphone but the result were not satisfactory considering how hard it is to mine this days. Please which coin can I easily mine with my phone.
Mining on phone does not exist in my understanding by now, maybe are you referring on those cloud mining site? Most of those cloud mining site is scam. But i have one suggestion try Electroneum. Its not actually mining on phone there is a real computer connected to your phone remotely. its just a visual interface. Maybe a marketing to give experience to those people who are not into crypto to have a preview of what is mining.
You can visit their thread here and read their whitepaper to understand more.
