How to get new profits from old miners due to the rise in the price of Bitcoin

According to CoinDesk, the first cryptocurrency has risen in price, which has affected the profits generated by mining devices.

If you look at the index that indicates the profitability of miners, which is tracked by the Pooln and F2Pooln mining pools, a device such as the Avalon A951, as well as the Antminer S9 (which are considered outdated equipment today), demonstrate an average profit of about 15% when electricity costs about $0.05 per kWh.

If we take measures to increase the efficiency of our devices, i.e. combine two S9 miners, and, alternatively, reduce the voltage, the earnings of miners will increase.

The upcoming rainy season in China may affect profit growth. What does this have to do with anything? But this very fact will be the reason why electricity may fall in price due to an excess of hydroelectricity.

If the price of bitcoin remains stable at its current value, such outdated mining models as the Antminer S9 will be maximally profitable even with halving. However, the same Antminer S19 or WhatsMiner M30 are considered to be the top equipment in terms of maximum efficiency today, and can generate earnings of 60% or more even at an average electricity price of $0.05 per kWh.
