LTC has lost it's cause. The founder sold most of his coins and got out of it and the volunteering team did tried to bring some changes but it was not enough. LTC originated as a cheaper and quicker alternative to bitcoin but as we know there are much more cheaper and quicker alternatives and a lot of others for manipulating investment as well as real use cases. There's no more reason for people to buy and hold or transact litecoin as there's bitcoin already and a lot more and better options.
