Choosing the right trading pairs is crucial to maximizing profits. For example, trading BTC/ETH is different from trading BTC/USDT, as the volatility and correlation between the assets can strongly influence the results. It's also important to check the liquidity of the pair: a less liquid pair will have a higher spread and make entries/exits more costly. Cross pairs (like ETH/BTC) can offer great opportunities if you understand the dynamics between the two cryptos. Before diving in, one must analyze each pair and adapt their strategy.
