Very idiotic POW algo Zcoin choose. Miner use 6GB+ RAM, 4GB+ Video memory.
RAM refilled every time with new job. Hashrate on 1060 6Gb is 10 times lower then before fork.

Absolute hashrate does not matter but relative one does.

This. High hashrates mean fast and simple hash functions, which are very ASIC-friendly, and it's not what the community wanted. It's also a bit like the Megahertz Myth of CPUs: do you care about real-life performance or a meaningless number?

Still, the memory requirements of Zcoin's current MTP implementation are quite steep. A 4GB GPU is not enough, you need 6GB in practice (as there are no GPUs with 4.5 or 5GB). This means only newer GPUs. A lot of people have GPUs with 1..4 GB VRAM, and they are now useless for Zcoin. Hash is being concentrated to those with the latest GPUs.

If the MTP miner only required 1 or 2 GB, we could distribute the hash to a much wider community. And I guess it would still be ASIC resistant, because a factor of 2 is not a deal breaker.
