What causes a slow Bitcoin (BTC) transaction?
Could you elaborate on the potential reasons for a Bitcoin (BTC) transaction to experience a slowdown? I've heard that the network's congestion, specifically the number of transactions waiting to be processed in the mempool, can significantly impact transaction speed. Additionally, does the transaction fee play a role in determining the speed of confirmation? I've also heard that miners prioritize transactions with higher fees, so could that be a contributing factor? Lastly, could you mention any other technical aspects that might slow down a BTC transaction, such as the size of the transaction or the complexity of the script? Thank you for your insights.
