To be honest, this is the first time I've heard of this. I have never seen someone ashamed of their work, or did not speak, if it is not a crime.
It's not about being ashamed of telling people that you're into crypto but it's about being protective.
There's the understanding that when you're into stocks, it's totally fine as it's what the rich people does.
Whilst in crypto, when you tell it to people, they'll be imagining that you are too wealthy and there were series of personal attack to people who owned crypto with the intention of stealing their crypto.
Not everyone understands about crypto and in fact many people still get misinformed about crypto. So some people do choose to keep it a secret
that they are actually investing in crypto. This is done as self-protection from negative things circulating about crypto, because there are still many
people who say crypto is illegal and a scam. Very much different from the stock market which has been known to many people for a long time,
so if other people know that we invest in the stock market, it makes us proud. Because most people who invest in the stock market are rich.
This is what makes some people uncomfortable if they have to tell others that they are investing in crypto. Things like that cannot be left alone,
we must dare to tell others that we are investing in crypto, explain well about crypto to others. So there will be more people who think positively
about crypto.
