The answer to the question "How long does it take to mine 1 Bitcoin?" is complex and depends on a number of factors, including the computing power of the miner and the number of transactions. For example, a Bitmain Antminer S19 Pro will take about 1,133.5 days to mine a single bitcoin, under the current difficulty of Bitcoin mining. This figure is even higher when transaction commissions are taken into account.
One of the first things to know about mining Bitcoin is that it is quite expensive. One bitcoin can cost anywhere from $7,000 to $11,000 on average. The price has recently dropped, but that doesn't change the value of mining a single bitcoin. It is also important to note that mining a single Bitcoin requires a dedicated mining pool or group of miners.
