Anyone who responds to questions or challenges about coin A with comments about coin B is a scammer, because this is an illogical argument that is being used to mislead observers and therefore fraudulently pump coin A and suck in gullible investor money to continue to prop up the scheme. This applies whatever coins A and B happen to be.

The only exception to this might be if coin B is Bitcoin and the question concerns general blockchain concepts since Bitcoin is the most well-known and understood example.
