They . . . say . . . you can easily loose all your money, etc.
. . . just gets a reply of "exactly" . . . you'll loose your money
They are right on that point. It is experimental, and extremely risky. It could be worth $10,000 per bitcoin (or more) someday, but it could also be worth $0 per bitcoin tomorrow. You should not have anything in bitcoin that would be devastating to lose.
The need is the individuals are my parents, and they dont want me to have ANY money in it, and are about to force me to withdraw everything ive put into it, delete accounts etc.
If you are an adult, then tell them that you've made your decision and you're ready to live with the consequences. Let them know that, while you appreciate their advice, you feel strongly about your decision to own some bitcoin, and won't be getting rid of it.
If you are a child, then you are probably going to have to do as they say.
