I was one of them and I told that to everyone that took the time to listen and some of them did.
This is why I was always doing the opposite - never talking about crypto to people in real life, cause I will become indirectly responsible for their investment, and it's likely to spoil our relationship if they will lose money with it, and this is not something I would like to gamble with. Plus people can lose money with crypto if they will fall to malware, scams or their own stupidity, and then they would still blame the person that introduced them, cause that's how humans work - they always try to find a scapegoat.
And I do when they ask me about my interests. I'm pretty confident in Bitcoin and those who know me know not to try that laughing stance with me.
I've been there when the price was 1000 dollars and I've been there when it was 20 thousand. There's really not much they can do to me. What will they say? That It was down 80%? Fine but now it's down 65%. If you bought in January and sold now at 7.5 thousand you'd double your money. What's funny about that?
