My dear, if you don't know the market, be careful!

I invested 2200 reais on 11/22/24, today 16 days later I have 2871, I earned 671 reais in 16 days and this is new to me. I have 7 thousand reais in savings and I'm thinking about putting it here, can any friend tell me in which currency would be smarter to do this?
Or should I leave it as it is and not put anything beyond the 2200 that I already put in? Thanks, big hug and may everyone have their income tripled 🙏🏽.
