Technical Upgrade of $BTC BTC**

The BTC network enhances performance through technical upgrades. Taproot in 2021 improved privacy, and in 2025, the Lightning Network increased transaction speed by 30%, supporting more small payments. For example, a coffee shop payment takes only 0.1 seconds. Layer 2 solutions reduce the burden on the main chain, lowering transaction fees from $10 to $2. Technological advancements add to its practicality, but the promotion speed is slow, and user acceptance will still take time to verify.
