Hey friends, I'm totally new to this. Sometimes I see that BTC or BTN dips or pumps. I want to buy or sell, but it doesn't let me. It tells me that I need to convert first; for example, I put in $5 and it says I don't have enough funds, but as you can see, I have $31... Other times I want to scoop up ETH/USD or SOL/USD when the price drops, and I get the same message. It says I need to convert first and then buy or something like that. Any advice? Any tutorials on this, please? I have several friends in this space who have made gains, but I’m clueless about it. I want to keep investing, but what's the point if I don't know how to grow it?
