I recently came across a mining topic, and I think it’s necessary to explain it clearly to everyone. Do you really know how long it takes a Bitcoin mining machine to mine 1 BTC? The answer may shock you—13 years. Yes, 13 years. And this is still under ideal conditions: no sudden power outages, no hardware failures, no increasing difficulty, and not even counting electricity costs.

Let me do the math for you. Take the Avalon A1566HA miner as an example—its hashrate is 480T. Right now, the total network hashrate is about 1.08Z, which is 1,080,000T. Each block rewards 3.125 BTC, and the network produces roughly 450 BTC per day.

From another angle: 480T accounts for a proportion of 0.0000444 of the total network hashrate. Using this proportion, the daily output a single machine can claim is about 0.01998 BTC. When you calculate it out, in a year that’s only 0.01998 BTC—so to mine 1 BTC, it really does take around 13 years.

But this is just a ledger calculation. In real life, there are a whole bunch of costs you haven’t accounted for—electricity bills, hosting fees, mining farm operating costs, equipment depreciation, and most importantly, the difficulty keeps rising. So the actual mining cycle will only be longer, not shorter.

That’s why real veteran miners never rely on a miracle from a single machine. What do they compete for? First is the electricity price—the cheaper the power, the greater the advantage. Second, whether hosting costs can be driven down to the minimum. Third, scale and efficiency: the cost structure for 100 machines versus 10,000 machines is completely different. Fourth, mindset—this isn’t a get-rich-quick game; it’s a long-term race against time, costs, and rising difficulty.

So if you’re still thinking, “How can a single mining machine mine a Bitcoin in a few months,” then today’s numbers might make you rethink whether mining is truly realistic.
