19 years old with $2K to invest into ETH but I know NOTHING. where do I start?

I’ just turned 19 and I’ve got around $2k AUD that I want to invest into ethereum. Don’t really care if I lose it as I’m looking to hold till ETH hits 10k. Problem is, I know next to nothing. I struggle to understand the terminology and lingo used in subreddits and articles. As of now, all I know is that to buy ETH I have to use Coinbase I think? Is that it? Honestly just looking for beginner friendly guides that start with the assumption you know nothing.
