What is bitcoin block time?
Could you elaborate on the concept of "Bitcoin block time" in a concise manner? I'm interested in understanding the specific interval in which Bitcoin's network adds a new block to its blockchain. Does this time vary? If so, what factors influence its fluctuation? Also, how does the block time correlate with Bitcoin's transaction speed and scalability? I'm curious to know if a shorter block time would necessarily mean faster transactions or if there are other considerations to take into account. Thank you for your insights.
