Bitcoin or non-Bitcoin-related investments are all extremely risky if you don't know what you are doing.
Even though other people say this is safe, that is safe, it's still useless. You can't guarantee what other people saying, it's easy to say something.
This is also the common mistake of new people who are entering Bitcoin or any other investment because they don't have knowledge of what they are doing. As famous sayings, "Don't invest in what you don't know".
