Buy BCH being under age

Well, I met BCH a few weeks ago by some friends. I spent several weeks researching it and I really enjoyed it, not because of HODL or something, but because of the brightness of the technology.

The problem is that I am under age. In my country, however, it is not allowed to open an account on exchanges without being over 18 years old. The fact is that I really wanted to be able to use, if only to test, a Bitcoin transaction.

How can I buy when I'm under 18 or get some? Following the law, of course
