I think you should continue to hold it. Because the bull market is coming in Q4. Keep as many alts as possible, because BTC dominates and investors will sell BTC to buy more. I suggest that you keep LTC as much as possible, halving is about to happen.
ltc is indeed an altcoin that will update in the near future. buy it is a good choice. but for other assets, especially new projects that don't update will be very bad. because they could lose their market immediately when they are not actively traded in the market.
