#TradingPairs101 in relation to the pairs, I believe that after trying some trades (I am just a beginner), I have found that one tends to play it safe or go with what they already know (vs USDT), but I have found some pairs that have better profitability, and I think it's because there are many people who do not use or check them. For example, with the ETH/BNB pair, I have achieved better profitability compared to USDT.
I believe this has more to do with a lack of knowledge than with profitability; it's somewhat similar to what happens with FOREX... normally, my acquaintances compare looking for entry mostly with USD or EUR, but there are many more currencies that, depending on other factors, provide better profitability, keeping in mind that crypto is much more volatile.
I invite you to look for trading options with pairs different from the most well-known or rather commonly used... for example, ETH/SOL... how they generally compete when one goes up, the other goes down, and sometimes it gives entry signals for doing some super profitable Scalping.
