...my total plotted files are around 80Tb. But the mined Burst is coming less recently, just ~3200 Burst per month.
What pool are you using? I have 58tb plotted and getting about 2,700 BURST per month on POCC 0-100. I found I got more in 0-100 than in 50-50.
I'm mining at pool.burstmining.club. I dont know how's about the pool rewards, normally I got average 55 Burst per day but even I found a block, I just got only around 830 Burst for that block.
