It shows that the users are seemingly sending and receiving more on-chain transactions, which might signify two things.First, it could show that more users are accumulating LTC and possibly sending them from exchanges to personal wallets. This means an accumulation trend might be in the works, as the alternative cryptocurrency (altcoin) market recovers as a whole.Second, there could be more users engaging in LTC transactions following various fundamental developments.LTC transaction volume is rising.

Since Litecoin and Bitcoin share similarities in structure, the solution can be implemented onto the Litecoin blockchain.It comes a month after CryptoSlate reported that a new Litecoin update showed the Mimblewimble implementation is on track.Charlie Lee, the creator of Litecoin, first announced the integration of Mimblewimble in January 2019. He wrote at the time:“Fungibility is the only property of sound money that is missing from Bitcoin & Litecoin. Now that the scaling debate is behind us, the next battleground will be on fungibility and privacy. I am now focused on making Litecoin more fungible by adding Confidential Transactions.”The confluence of major network developments, growing transaction volume, and the beginning of an altcoin season buoyed LTC in recent weeks. In the short to medium term, LTC could see sustained momentum if the daily active addresses begin to increase and social volumes remain stable.Litecoin, currently ranked #6 by market cap, is up 4.91% over the past 24 hours. LTC has a market cap of $5.66B with a 24 hour volume of $6.26B.Litecoin Price ChartLTCUSD Chart by TradingViewLike what you see? Subscribe for daily updates.
