Yeah, I mean, just do the math. If you mine 50k ESP per day, you're better than going to a pool.
Once I don't find a single block in 2 or 3 days or more, I'll consider a pool.
you're better to not mine at all, because you're losing money, with the huge supply i doubt you can even see 5-10 satoshi for this
Eventually, it will get to the point where mined is just a little bit more than electricity. That should stabilize in a few weeks or a few months, maybe.
It took bitcoin 6 or 7 years before miners decided to drop. Or get new hardware.
I think ESP will have a GPU miner one day. Hopefully not too soon. Then everyone will be mining on GPUs. Depending on how well the coin does, we might see some attempts at FPGAs, or ASICs; those will take a few years.
