Why ? JeanLuck kangaroo keyrate is 1 Giga, I use kangaroo what 55 terra, and I was try BSGS what 500 Peta(but I no so like BSGS, kangaroo I like more), so WanderingPhilospher make his own soft what has exakeys... If you use dead software this not meant what other uses so software 2.
Well you might be right about BSGS (but I have never used that software before so take this with a grain of salt), but I don't think you can hit 55 terakeys per second on kangaroo without a GPU farm and leverage the kangaroo server feature.
Maybe they have ...
Do you know, if there are already asics like these

not to mine coins but for point addition?
