People dealing with sceptical family or friends, what are their arguments against crypto?

Even if crypto has already been around for a while (with many well-known personalities embracing it, governments the world over getting involved, etc.), there are still tons of people who don't even know that much about it, people who know a bit more don't care about it...

...and people who are pretty much sceptical about it, and sometimes even vocally against it.

As members of a large community devoted to cryptocurrencies, what is your experience with family members, friends or coworkers who don't trust crypto?

Do they have specific doubts or fears? Are they trying to talk you out of getting involved? What are their most common arguments against crypto?

I think this is a very interesting conversation to have, not just for our own sake (for example, less strife at the next family gathering, lol), but also for founders and communicators in the crypto space that might want to find new, better ways to promote their projects and make them more accessible to a wider audience.
