If the BK-X is not an FPGA miner then why would Baikal ask customers which algo's they wanted to see next? If the algo's are already baked into the hardware they should have said "which of the following do you want to see released next". Not a wish list of algo's you want to see.
where did you see , they ask that ?
If i can choose , in this range of H/s (5gh ~10gh) , without hesitations, the best are
phi1612 and
Timetravel10But as Lux ever pretenting can fork , even against FPGA, think it's pretentious but probably they dont want fpga and asic. so may be
skunkhash instead of phi1612
