An Asicminer Blade is 10GH, so 1 PH is 100,000 of these. That is a lot of hash power to mine bitcoin.
No one mined with Asicminer Blades since forever, because obsolete.
Asicminer folded & ran away with people's coin a couple of years ago.
The current hashrate is 1,529,415,029 GH/s or about 1,529 PH/s.
10 PH is less than 1%.
