Litecoin is still one of the top 5 cryptocurrencies and everyone should invest in LTC. It is no longer the “silver” to Bitcoin’s “gold” but it still trades very well and still has lots of development around it. The acceptance of cryptocurrencies has been extended to governments. Let’s take Japan for instance, a market highly accepting of innovative technologies, recognized Bitcoin on April 1st, 2017. It is also set to standardize blockchain technology. There is a clear uptrend for the four largest cryptocurrencies (Bitcoin, Litecoin, Ethereum, Ripple) around the time of recognition. Russia is also attempting to legitimize, as it would help the government crack down on money laundering.
The greatest barrier to widespread adoption is acceptance. If you can’t use it to buy a coffee at your local shop or a train ticket at the station, no one will use it. However, Litecoin is going to (being) be adopted by large companies.
