It sounds like you’re facing some tough times with mining! The profitability of mining can definitely fluctuate based on a lot of factors, like network difficulty and coin value. As more miners join the game, it can get tougher to see those returns.
Looking ahead, I think the future of altcoin mining will depend on a few things: the overall market trends, the development of new technologies, and how different coins adapt to the changing landscape. Some altcoins might find ways to improve their mining efficiency or offer better rewards, so it could be worth keeping an eye on emerging projects.
In the meantime, you might want to consider diversifying your mining efforts or even exploring other ways to earn from crypto, like staking or yield farming. Just keep experimenting and stay informed!
