Ethan Vera, chief operating officer of Luxor Mining, who previously operated the Ethereum mining pool, tweeted that too many Ethereum miners have transferred to ETC, even if they run a new generation of hardware at less than 3 cents, it is currently impossible to make money on ETC. Overall, around 20-30% of Ethereum miners have migrated to other networks, with the rest currently shut down. Also, according to Minerstat data, a block reward for mining ETC about 24 hours ago was 0.01330791 ETC, but has dropped to 0.00027668 ETC in the past hour.
