I'm not sure about my stand but for me Bitcoin Clones cannot succeed unless we reached adoption because Bitcoin can support the needs of the users now and there is no sense of using LTC while bitcoin is existing this strong .
But of course there are chances in the future , but what made me think is Why did the Owner sold LTC in 2017 ? if this has a Bright future ahead then he may preserve this as is?
But that's not what happen , instead selling is what he did though LTC is growing strong again after 3 years .
