Litecoin not sure, I havent research Litecoin in a very very long time, sometimes I trade coins without knowing what they for just based on chart but XMR I think its something the entire space is overlooking, once US and China make their digital currency mainstream is when I think privacy coins will kick in for now most of the crypto space dont use privacy coins features at all but yes XMR will be another big asset, another privacy coin I like is BEAM
