I find that the only reasonable competition to SP30 would be ANTMINER S3 -B5 and it is shipped on 7th August.
What about this beast?
This is exactly what a 3KW miner should look like. Spondoolies should take notes.
You should take note that Bitfury uses customer funds to build mega farms and screw their customers ROI.
maybe it screws roi in terms of btc.
but maybe it keeps btc price higher in terms of usd. (pick any currency)
bottom line for all of us is keeping the btc price high enough to bother to mine.
and I had around 1k into bitfury gear that was built and not delivered . I got a refund instead.
this is a very tough business for miners. just the way it is.
