It appears that Zcash is a sophisticated SCAM and they are in cahoots with Bitmain, I have never seen a POW fall to ASIC so quickly, they must know of a backdoor to speed it up by a factor of x10 and their aim was to make money selling mining machines which is guaranteed income and to control the market; these ASIC have been mining since around middle of last year.
SPREAD THE WORD.
NOTE: signs of a scammer differing in giving straight answers to simple questions. Stated in their mission statement ASIC resistant now not so much, inform people of the SCAM to avoid it.
