good morning detective Columbo!

forget about BFL, not worth it at all!!

well there is no peace of gear worth of buying right now. there is no 1TB miners available on the market unless you want to by 5 antminers or stuff like that.

your only option is to buy 2TH black arrow late February delivery miner.
just don't forget that with this wild diif jumps in about 3-4 months everything below 1TH will be worthless!
