Let's say I am under 18 and made like 120 dollars trading shit coins with Solana. Would I have to file taxes on that? I got a little bit of Solana from the helium app, transferred it to a personal wallet, and made like 120 dollars off a less than 10-dollar investment. Do I have to file taxes this year or should I just wait till I'm 18 in like 8-10 months?
