Electroneum tokens are not Ethereum based tokens , They have there own blockchain , I think there is still a chance to buy some tokens , The sale was suppose to end at 31 October but I see people talking about hard cap of 40 million and we are now close to 38 million if that is true you can expect the ico to end in a couple of days . As for mining app my last update was ,  It  will be release at 1 November , But if ico ended early I really dunno what will be the plan .
