There is always risk involved in crypto, that's why you are seeing that kind of warnings. And there's risk aversion as well, so it's really up to us on how to manage it. So personally, I don't see that there are different though, risk is a risk. The big question is how you are going to mitigate the risk? Do you have plans?
Yes. Once you're into crypto trading, the risk will always be there. This is the reason why you should only invest what you can afford to lose because in trading, there is no guarantee if you will make profits most of the time. One mistake will surely left you empty handed if not being controlled. I don't think there are different level of risks. The only concern here is how you will take the risks and overcome it.
