The only miners making a profit either already have theirs in hand or will have the next-gen's by end of this next week. Difficulty has risen to 4PT in a span of three weeks when it took years just to reach 1. HashFast's "Miner Protection Program" is the only offering at least promising returns. The rest of the miners were rushed to market and skipped a number of standard steps in their design, testing, and manufacturing processes. I'd buy straight bitcoin if I were anyone seriously considering an investment.
