I think electroneum is a good idea with some potential , after launch his price drop down for some problem in the day of launch (fixed after 10hour) but mine it make really a lot of money , I try mine for one day monero (atm have high difficulty) 2 days (for a total of about 15hour at about 800h/s I earn 1.2$) at same time with same program and same PC I earn 50 etn that are 3.5$ I earn more than double then monero!
Mine etn is very easy, wallet is on mobile and is very good, safe and fast
For mine I use xmr stack (usually used for monero but good for all cryptos with cryptonight algorithm) good mining to all ;)
