Too many massive players have a complete monopoly over Burst now.
Just look how many 1PB rigs there are.
I mean for me, in the UK, 1 PB, using 8TB external drives would cost me £18,750 and would earn me £290 per month, so 65 months (Yes over 5 years), just to recover my hardware costs.
Also, that many drives are not cheap on electricity, despite popular belief.
So unfortunately, much as i like Burst, and still mine it with 32TB (max i can do via solar power - so free) to me at least, its mining time has been and gone.
