always invest in bitcoins, because it is the only one that the government cannot control. If the US invests 20B under Trump, the price will explode and countries will be forced to invest

I'm starting to invest and would like to know some recommendations. I'm 15 years old and I want to invest 100 reais or less per month for now.
I'm thinking of getting to at least 20 dollars and putting approximately 50 reais in Solana. I don't think it's worth investing in Bitcoin, but if someone tells me some reasons to invest in it, I'll probably invest.
In short, I'd like recommendations on where to research about it, people who know a lot about it, and your opinions.

Sorry for the bad Portuguese.
