Its a good machine, but in current market not so much better then GPUs. Specially considering the price. I would go so far as to say that with cheap power its even worse because you cannot speculative mine new coins.
at the moment it may be better for a guy with 10 cent power
then a guy with 3 cent power.
Can you elaborate, I missed the point. Maybe I am just dumb lol.
However I still don't see the value in these miners. As said they are good machines, easiest to use FPGA, but in the current market FPGA are not as good as they were advertised. Buying mining equipment at this time is a gamble for sure, but with GPUs I can mine Grin, BEAM, Veil or any new coin that just came out and at least score a jackpot from speculative mining or join an early train with some profitable coin. For instance if ETH goes ProgPow I can mine it with GPU but not with FPGA. And you are also dependent on the algos they provide. The profitability would have to be way better for such limitations and thus the ROI shorter. 2 year ROI is just not going to cut it.
