there is no such thing as ASIC-resistant.
that term is like a buzzword that some altcoins started back in the days only to advertise themselves as a coin that can always be mined with GPUs. but the fact is they changed the algorithm so that bitcoin ASICs can not be used for them.
in other words the correct term is BTC-ASIC-resistant. but nothing is stopping a company from creating a new ASIC that can mine them.
