I was under the impression that Electroneum was pre-mined when it comes to cell phone usage and its mainly just an incentive to keep it running. I'm not big on the Electroneum project but however you slice this, it feels really gimmicky... it may would be cool if "only" cell phones could do it so hash power wasn't so ridiculously lopsided, but people will find ways of exploiting this almost guaranteed.. imagine an asic emulated Galaxy S9 miner.. lol.
