Unless you have very cheap / free power they are not worth much.
With free power, at today's prices and difficulty those make up to 120$ a month on Nicehash, however, the altcoin mining profitability is a roller coaster, so that might not hold for too long, the next day it could be 1$, so it's not even easy to know if they are worth fixing, mining any Altcoin except for LTC and Doge is a massive risk, it has always been since ETH moved to PoS, I really hope people stop wasting their money on these altcoin miners.
