Everyone keeps telling "do not mine, it's not worth anymore". But why? I have been mining scrypt altcoins for 1 month now with 4 GPUs. The electricity is about 30-40% of the revenue, the rest is pure profit. I bought and built the rig myself. The GPUs are used ones, in good condition from e-bay. The whole rig costed about $1000. I earned 25% of it in the first month and planning to build another one next month.
According to my experiences is DOES pay to mine. It is not an easy work, fine tuning and continuous monitoring of the hardware is essential.
I do believe it's definitely worth it and a fun thing to do. Don't agree? Why not?
It's a risk no matter how you look at it. If you're making money then keep at it, but there are a lot of variables at play that make it less profitable for some people. Electricity costs vary and not everyone knows what they're doing when it comes to putting a mining rig together. When people say "don't mine" they're not saying that absolutely no one can make money in the current state, it's more "If you have to ask, it's not for you"
