I've dedicated a lot of my life to this particular branch of cryptography, I've learned a lot! But it kinda feels like it was for nothing at this point. I've publicly released all my crypto projects source codes and walking away from developing in this sector.
I'll still be around speculating but that's about it.
Can for now say you should be courageous to defeat any affliction but don't get yourself forced in to keep riding on the cryptography space. Locate what works better for you and hope you don't turn a critic out of your unimpressed experiences.
The rewards of miners has become belittled due to miners scalability so, the intrinsic means single miners can make good earnings from mining rewards as the pool becomes competitive is you merging your hashing power to others so at time of rewards, your earning points of rewards would be increase.
Left alone not being affiliating with others, you will earn very minimal such as the situations you are in that reward values can't even pay your bills.
In cordial response, there is no playing as cheat about it. The system changes is basically due to higher numbers of miners now.
