This is a sort of misinformation, I guess as Nasdaq never say that was a scam...they even praise Litecoin and crypto.

I don't look for the others as they probably speak the same towards Litecoin. I don't know where you get that information or just something you are acting differently and ruining their names (sorry). And besides, people had already know about Litecoin, a known and top listed coin turns to scam? That is something is unreliable.
