The confusion must come from that middlecoin.com pays in BTC while mining scrypt coins. There are currently no scrypt ASIC miners out yet. There are some in development and in pre order state such as the Alpha Technologies one from alpha-t.net. Still thinking myself they are a scam when looking at their company name changing four times last year and the name of the owner/director changing 3 times. Approach with caution!
Middlecoin is a scrypt coin thus BFL equipment won't work.
Thanks a lot you both saved me a lot of time. I just set these up last night and don't know much about mining yet. Middlecoin seemed like it made the most sense but I guess I'll have to join bitcoin or altcoins pools for now.
