Litecoin! The second oldest coin, instead of others (FeatherCoin), Litecoin still exists and work perfectly. Many people think that Litecoin hasn´t future because it doesn´t bring anything new. No? Look which coin come first with working Lightning Networ. Privacy feature will be added soon, so, maybe it could replace Monero?
Agree. Litecoin is very undervalued and under the radar of most investors and traders in the crypto market. It's a cryptocurrency that resembles Bitcoin in every way. With a limited supply of 84 million LTC and a block reward halving just like Bitcoin, it should've been worth a ton of money right now. I guess that most people are into the next big thing in crypto than anything else. They only care about cryptocurrencies with shiny new features, instead of those that are stable and resilient with a tried-and tested Blockchain network. The Mimblewimble privacy feature, will make LTC unique from Bitcoin and most other old coins on the market.
At current prices, I believe that Litecoin is still a bargain these days. Its blockchain network is healthy too, after all these years. For a cryptocurrency that has been often abandoned by everyday people in exchange for other big coins on the market, it has done impressively over time. Litecoin is still among the top 10 coins in market cap, which means that there's still demand for the good-old coin. It shouldn't be long enough before the adoption of Mimblewimble brings higher prices per coin in the future. I don't think that LTC will be able to replace Monero in the long term, since its privacy tech is a completely different thing. Monero will always be the "king of privacy" because of the features it provides. But rest assured that LTC will be used more than BTC as people look for an alternative to Bitcoin that focuses on privacy above anything else.
Nonetheless, LTC is a good-old coin worth holding these days. Other coins like NMC, PPC, BLK, and XPM, are good too but people have "overlooked" them because they're focused in the "new kid" on the block. Even if they stop trading on the market, there's nothing stopping anyone from reviving the project. The open source nature of crypto, allows anyone to carry on with the project if it becomes abandoned in the future. What matters is not the underlying cryptocurrency but the core Blockchain technology itself. As long as you can put Blockchain tech to good use, nothing else matters. Just my thoughts
