If you use a smartphone then you really need to look into Electroneum's mobile wallet app which basically gives away Electroneum(ETN) for free by simulated mining. It doesn't actually mine ETN but only simulate it by guessing the hash rate of which you would get if you actually mined on your smartphone's hardware. I currently get about 30H/s to 31H/s which equals to about 5 to 10 ETN per day depends on how long you run the app per day and they also keep Mobile and actual mining difficulties separate. It also has a referral program. By referring others with your code gives you 5% bonus depending on what they earn. And people who use your code also get 1% bonus. (You can use my referral code DF8F34 if you like)
ETN's value is around 0.02 USD as of writing and currently ranked at 97 with a total market cap of 144,706,049.00 USD with 7,113,239,266.00 ETN in circulation.
