yeah  I use the sticks for fun I hit a PPC block with

them.

I look forward to some more efficient models.

At the moment  BTC  is in trouble.  but there is a lot of $$ invested in it.  I am sure it will do better.

I mine my eth directly into btc  as I prefer btc. I use nicehash

But asic mining of btc is in trouble.

look at this rig the pandaminer.  it is far better then the s-9

I point it at nicehash  i get about 0.02368 btc per day using about 1050 watts

I need 44 th of sha256
 or 3 ½ s-9s to earn 0.02368 btc per day

and that is 4500 watts

this math is what it is and is causing price adjustment in coins.

So at the moment my btc is cheap  via  eth mining
