Litecoin on-chain metrics are as paltry as it gets. The blockchain recorded only 21k transactions in the past 24 hours, which is 10x less than bitcoin and 150x less than EOS who is leading the market in tx numbers.

Not only that, but the block sizes are, as Paul Everton highlighted, well below 30kb meaning there is simply no transactions on the network to fill the blocks so miners pick up the block rewards by mining almost empty blocks.
