Some cryptocurrencies adopted asics resistant algorithm
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.
I am less active than before in the altcoins sections and news but as far as I know all asics are made to mine bitcoin in the first place?
ASIC is not even about mining. it is basically an electronic circuit that is designed for a specific use. a bitcoin miner is a type of ASIC which is short for Application-Specific Integrated Circuit. but ASICs have other usages too.
in crypto space so far since bitcoin has been the most solid Proof of Work cryptocurrency that is worth mining the focus of ASICs have bee on mining bitcoin's PoW. but there are other ASICs too. for example the scrypt mining ASIC that is used for mining litecoin (called Antminer L3) and recently Ethereum ASIC miner (Antminer E3)
