No

Yes

Probably not.

FPGAs aren't talked about much because they are VERY expensive to purchase and operate. They will also will be slower and are much more difficult to develop for than GPUs that cost significantly less than them, at least for the majority of algorithms. FPGAs really only pull ahead of GPUs in a few very specific algorithms, like bcrypt. For everything else, they are usually quite a bit slower but potentially more power efficient at least.

Let's say the cost of the FPGA is $4 bucks. If I buy more, the price goes down to $3.  The reason it's good for Bcypt is the code was optimized for mining for Bitcoin. Mine would cover 80% of the hashcat algorithms. It's all about what you algorithms burn on the chip.  The Power would be less than running the same process in a GPU, like 2/3 less power, that is where I get the less cost for running a long time.
