Why are Bitcoin transactions sometimes slow?

Bitcoin transactions can be slow due to several reasons. One primary factor is network congestion; when there are too many transactions, the network’s capacity is exceeded. Additionally, the block size limit of 1 MB restricts how many transactions can fit into each block, leading to delays during busy periods.

Another factor is transaction fees. Users who set lower fees might experience longer wait times since miners often prioritize transactions with higher fees. Lastly, the need for multiple confirmations to secure a transaction adds to the delay. These elements combined can make Bitcoin transactions slower, especially during high activity times.
