Electroneum is a cryptocurrency with special features. i remember when electroneum was introduced i have problems for mining with my mobile phone. electroneum ICO is one of most succesful ICOs i ever seen. TN use monero blockchain codes and its gave us a good way to mine with mobile. actually i was expected electroneum gave us a good rate to mining but it is only use normally CPU mining rate of our self phones.
about design of their website and applications i have to say it's one of the best designs i ever seen.
