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.
That honestly sounds like a touch of paranoia on your part--but on the other hand, I don't know what people you're talking about. If I told friends/family/coworkers that I'm into crypto (and I have), the last thing on my mind would be that they'd jump in and compete with me. In fact, I'm usually met with complete indifference when I mention bitcoin to people.
As far as being secretive, I'm not. I think I should be more discreet about my dealings, though, simply because there are so many scammers around and I just never know who to trust. That's on the internet, though. In real life, I don't care who I tell. Nobody I know owns any crypto and quite a few of the people I've mentioned it to have barely even heard of it.
Exactly. There should be no hiding about what coin you have invested in and what coins do you plan to invest in. I think if you tell people about the coin you HODL, it will not affect the growth or value of your coins but might help them muster up the courage to invest in crypto. They might be looking for guidance maybe and not always try to laugh at you or try to be better than you.
