After research, I managed to identify how Bitcoin mining hardware is evolving for times close to #halving .

An S19 PRO Hydro 250TH/s 5200w ASIC miner is a specialized device for mining Bitcoin and other cryptocurrencies based on the SHA-256 algorithm. ASIC stands for application-specific integrated circuit, which means it is designed to perform a single function very quickly and efficiently. In this case, the function is to solve complex mathematical problems that require a lot of computing power and electricity.

The S19 PRO Hydro 250TH/s 5200w ASIC miner has the following features¹²³:

- It is manufactured by Bitmain, one of the leading companies in the cryptocurrency mining market.

- It has a hash rate of 250 TH/s, which means it can perform 250 trillion calculations per second.

- It has a power consumption of 5200 W, which means you need a high-quality power supply and a proper cooling system.

- Uses a water cooling system that improves energy efficiency and reduces noise and heat generated by the device.

- It has an approximate price of 207,947.00 CZK (Czech crown), which is equivalent to about 7,500 USD (US dollar).

The profitability of a S19 PRO Hydro 250TH/s 5200w ASIC miner depends on several factors, such as the price of electricity, the cost of the device, the difficulty of the network, the price of the cryptocurrency, and the mining pool commission. According to a mining calculator, the PRO Hydro 250TH/s 5200w miner could generate about 8.97 USD per day, assuming an electricity cost of 0.12 USD/kWh and a pool fee of 1%. However, these values ​​may vary depending on market conditions and device configuration.

Before evaluating these costs, you should have a price target of #Bitcoin for the end of the equipment's life cycle, in 5 years the BTC I think will be worth 84,000 USD and the cost of mining it will be 38,000 USD, not including solar energy.
