I just saw this on a blog. Indian based blog. How possible really is mining bitcoin through your mobile phone(samsung galaxy s5 to be specific).
From what i saw. It seems that the samsung company set the phones like those hardware miners. Theyve also stated that a 7 samsung galaxy s5 can mine faster than the i7 core gpu. If this is really a success it could really be a big help for us. We can easily buy some of this 2ndhand samsung phones and can easily be in the business
