Why does "nobody" talk or even know about cryptocurrencies?

I dont mean us with "nobody", but people around us.

Without saying that I invested in crypto, I tried to poke around and subtly check out if people know crypto:

• Nobody in my workplace knows what cryptocurrencies are

• none of my friends know crypto

• almost noone in my family (except for one cousin who is a shitcoin degen, but I don't count him, because he is just a gambler) have ever heard about crypto

• those occational random encounters on bus, train, whatever...smalltalks. They are completely clueless about crypto.

So in my view, it feels like 98% of people don't know cryptocurrency and 1% are thinking that it is a ponzi.

The rest 1% who have heard about it:

• either thinks highly of it AND have invested in it

• or think it's good, but don't invest in it.

Cryptocurrency is still so unknown and/ or misunderstood.
