good to know

I have a question, until now I was trading with $EUR because it is more relevant to me. But I feel that if I convert everything to $USDC I could gain more. When I sell at a profit and wait for it to drop, I could have 10% flexible capital, and with events, I regularly need USDC. What do you think? Should I switch to USDC?

I will have to adapt to the rate if I change everything, that’s what worries me the most. Currently, I have buying and selling prioritized but based on the euro.
