When it comes to cryptomining and newer mining machines, we often only come across loud marketing texts, but sometimes it’s worth looking a little deeper. In the case of Bitmain’s Antminer S21 series, it can be said that it is worth paying attention to, whether it is air-cooled or water-cooled models. Is this series really worth as much as it is being pushed on some forums? Bitmain Antminer S21 is basically very powerful, but you have to pay attention to the conditions. If we only look at the documentation, then the air-cooled versions generate roughly $7.43 per day, while the water-cooled models generate $17.34. But this is only the first time it looks so rosy. With the increasing hash rate and the upcoming halving, profits can take a nosedive quite quickly. The air-cooled model of the Antminer S21, which is produced in roughly 50-100,000 units per month, has a hash rate of 200 TH/s, while the water-cooled version can reach up to 330 TH/s. In terms of energy efficiency, the air-cooled one is 17.5 J/TH, while the water-cooled one is 16 J/TH. Added to this is the price as a factor, which is roughly $14 per TH. So an air-cooled Bitmain Antminer S21 costs $2,800, while a water-cooled one costs around $4,700. The price is expected to rise anyway, so according to insiders, those applying for such a machine should hurry. And if we multiply by the promised profit of $7.43 per day, we can reach $2,713 in one year, so the machine can pay for itself in almost a year. With the water-cooled, this is an even shorter interval for payback. But let’s not forget that there is more to Bitcoin than that. The difficulty of mining, the change in the price of Bitcoin or even the volatile market can all overturn our mathematical calculations in seconds. The decision is ours, the possibilities are good, but it is worth making a deliberate decision and constantly monitoring the changes.
