Hi!
I'm a cryptocurrency newbie and have very basic/dumb questions about regulation. Here goes..

1) What does regulation mean in practice? Is it like they want to register people who invest or something? Is it all about taxes?
2) Why does governments want to regulate crypto?
3) I see "securities" a lot when googling regulation. Are only coins/tokens that governments deem to be securities in danger of regulation?
4) What are the drawbacks (& advantages?) for an investor who discovers his/her crypto investment is to be regulated?

Thank you for your time & patience
