When people ask, What do you do for a living? I have a full time job, but I also trade crypto-currency. I do not like telling them about my currency and Bitcoin activities because when I tell people about trading currency online our relationship sometimes changes. They start scheming or they think "I can do that, better than you" and I suspect they want to secretly start trading too.
Does anybody relate to this?
Simple, if you don't want to, don't tell anything to anyone.
There's no need to show over-smartness about your trading strategy or anything related, because that will lead to breach of your pledge towards decentralization and privacy maintenance. It is good actually to keep our mouth shut over things like these as we don't know who's got what intention and may turn out to be whom later on.
Why would they 'want to' start trading secretly when you said that they compare themselves with you and yell at you that they are better than you?
