Lets study something about human nature.
when do we say bad words about something?? only out of disgust or frustration or when we dont get out of something what we expected.

So no sane mind would believe that Isle has actually earned profit and after earning profit he began saying bad word about electra. there is no good reason for doing that. atleast humans wont do it. thats human nature.

the only reason i could of think of is that he obviously bought ECA when it was high. he believed in ECA coin but he is weak at heart, so he sold his coin when ECA began to come down and bought this nexus which was going ok when ECA was coming down. but he got late in catching that train too. now nexus price is dipping with each day and ECA is steady n rising back and this makes him even more angry and he is using more bad words here for ECA and its members.
he is a poor guy and playing catch up and getting more n more frustrated with each day. please dont give him much importance. he might be not in good mental health after all the loses. after all its hard earned money.

I hope he could come back to ECA because he believed in this coin before investing in ECA and should stick to it. He will get back his lost money.

Best of luck.
