The rise in the price of BTC has positively affected the profitability of the mining equipment, which was considered obsolete. This was reported by CoinDesk.

According to miner profitability index, monitored by PoolIn and F2Pool mining pools, out-of-dated equipment such as Antminer S9 from Bitmain or Avalon A851 from Canaan show a gross profit of 10-20% at an average cost of US$0.05 per kWh.
Even greater profit growth can be achieved by those, who have taken measures to improve the efficiency of their devices, for example, by combining two S9 miners or reducing voltage.
Profitability may also increase due to the coming rainy season in China, as electricity prices may fall due to excess hydroelectric power.
If the current BTC price is maintained, old miners such as the Antminer S9 will be able to generate profits even after halving. Newer units such as the Antminer S17 and S19 or the WhatsMiner M20 and M30 can generate over 60% profit even at an average electricity cost of US$0.05 per kWh.
