I hope, some years down the line, you take the broader life lesson that anyone promising you money for nothing does not have your best interests at heart.
On another note, one thing about Coinbase that struck me, was that on the app/website it doesn't actually show you how much money you put in / what the return on your investment is (I used a spreadsheet to track my own investment "success").
I suspect Coinbase does not do this deliberately - as many, many people who invest in Crypto lose money and it doesn't want to highlight this point too much.
Likewise, you could withdraw your bitcoin to your own wallet for free. The fee comes when you change from one type of currency to another.
I think the reason they don’t show return on investment is because Coinbase presents itself as an exchange, not an investment platform. The purpose is to facilitate the exchange of currency from one kind to another. They’re not positioning themselves as trying to help you build up retirement nest egg.
I am not positive about the future of crypto though. And I said before it's also telling that I had to use a spreadsheet to look at how much I put in, fees, money lost etc. On Coinbase. Again I suspect it's because a lot of people are losing money and the owners want that information hidden.
