to date there is no asic for ethereum. and most likely will never be with an ever-increasing DAG file and pos on the horizon.
There are many scammers out there promoting[ websites that are fake or scams
That is incorrect. Bitmain has been giving information that they have made one, and are working on it. Ethereum is supposed to be ASIC resistant, so an algo change to disable ASICs is supposed to occur but looks like they dont really care if the ASICs come in.
This is incorrect. Bitmain hasn't said a damn thing and never will until they release one.
It is some random Chinese website that said they may be working on one.
If you are waiting for Bitmain to make the announcement then you will hear about it when it is listed for sale. Its basic knowledge that something is being created and done, and even when there are more than 1 website stating specifics into the machine, and even sources that prove that they have been working on it. If you were to read more into it, you can see there is proof that they have been acquiring the RAM required, and producing an ASIC for ethereum. Bitmain does not announce anything until they are up for sale, because they dont want the public to know they have already been using it for months and selling off cleaned up units as brand new.
