we all know it is a crappy market now, but the message you are trying to convey is that all miners should just quit mining.
will FPGA save it all? no, it is just another tool in the box, it stands out due to its easy configuration and power efficiency and low heat, compared to the "old cheaply" gpu mining. this fpga chip is the best you can find in the market, in terms of performance per watt/per dollar. we think it is pretty cool to have for mining that's why we are making them, but if you are talking about ROI, i don't think gpu and asic are getting anywhere better.
Estimated hashrate table:

One more "crypto mining" FPGA board which will never ROI.
lyra2z is already decimated by bcu1525 and private chinese fpga farms. The last one coin with notable emission GINcoin is forking withing near week or so.
6Mh/s on Phi2 algo earns 5 to 15 cents per day with electricity at 10 cents/KW. Even old cheapy $70-100 rx480/580 Polaris hash the same 6Mh/s on this algorithm.
Lyra2rev3. Current profit is 20 cents per day. This is 5+ years payback period. old cheapy $70-100 rx480/580 Polaris hash almost the same ~45Mh/s with barely OC and ASM optimized miner.
Tribus, Keccak, 0xbtc, XDAG algos are dead if speaking in terms of profit
No one public available fpga board with a public bitstream can ROI mining cryptocurrencies, especially in current market state.
I want to repeat: mainly only miming hardware manufacturers and hardware resellers earn money in crypto mining sphere.
Currently crytpomining is a zero-sum game, where miners will always lose, doesn't matter what kind of specialized hardware you are using : ASICs, FPGA.
Take a look at bcu1525, Acorn owners. They all screwed, there are no chance that they'll be able to payback investments even within 3 years period
Please don't call me overly pessimistic. I'm a realist who is familiar with math
