Recently i found Tweet of Litecoin Developer David . Regarding Mimblewimble implementation . I think it would be the great implementation in litecoin network even it is initially proposed for Bitcoin also but now its going to implemented in Litecoin its great .
If you really missed to invest on eth before ethereum 2.0 launch then it is the time investing on Litecoin before it is getting bigger
Mimblewimble in simple words Giving option to the user make the transaction private . So that no one can look into your wallet based on your transaction details .
