An ASIC miner is capable of one thing and 1 thing only - mining BTC.
I am not disagreeing with anything else in this thread, I haven't even reviewed it and feel confident that the others here have it right.
But I could totally imagine someone creating a "provably fair" gambling thing which they custom designed to be hackable with an asic miner, so that they could cheat at it themselves.
Of course, scamming people can be accomplished much easier today, but one should be careful with the absolutes. There is basically no scam too stupid or too contrived for people to eventually successfully use it against crypto users.
Consider the almost constant stream of ECC key cracking programs that show up in this subforum that are nothing but wallet stealing malware.
