Crypto - SOL

Hello. Although I'm constantly looking for different ways to make money and assets to invest, I don't really trust cryptocurrencies. It is not clear what it is backed by and is very volatile. In addition, 80% of all new coins turn out to be scam. I'm more of a forex fan (roboforex). Everything is more clear there. If a country develops and grows its economy, the currency becomes stronger. This is, of course, very roughly speaking.
