Today I upgraded my crypto portfolio by adding $BTC and removing some smaller coins that were not performing well. I believe $BTC is a strong and trusted coin, and it has been in the market for a long time. I want to focus on coins that have real value and are used by many people. In the future, I also plan to add $BNB because it is part of the Binance platform, which I use every day. Keeping my portfolio safe and balanced is very important to me. I will continue to learn and improve my portfolio step by step.
