no it is not speculation  as r-box are the best small scale device for solo -pool mining .……


While I may be annoying you  and I apologize for that.   I am looking to expand BTC  in a way people can relate to.  

 These are a great device to point at a pool that pays only the block maker (is that better name then solo pool) .  or how about
 
www.blockmakergetsitallpool..com/philipma gives this name

 

 I point them at bitsolo.net  3 of them.  the current cost is  2.50 for the 3  pointed for 1 day.   or .83 cents a day for one.  that is with diff at 13.5 and power at 15 cents a k watt

then I point them at btcguild  for 6 days.    where they earn about 2.05 usd x 6 or 12.60 usd  for the 6 days.
