I wonder whether the developers will change the algorithm or all the same will be a coin for ASIC

I'd treat it as fake and a scam for time being. Never heard of them and they misspelled Baikal on their website.

Not worry because a lot of coins still keep lyra2rev2 asic algo, ignore HDAC not a problem.

Hashrate HDAC - 8.47 TH !!!
MONA - 4.59
VERTCOIN - 1.43
VERGE - 0.43

No one cares about HDAC, #1730 out of 2112, aka not even relevant.

As long as VTC / XVG / MONA remain on Lyra ASICs will continue to run.
